TORQUE vs HORSEPOWER Explained In Less Than 3 Minutes
Вставка
- Опубліковано 29 вер 2024
- Torque and horsepower are two important concepts in the automotive industry. If you need to move big loads, you need torque. If you're in Formula 1, you care about speed. In both cases, you need horsepower. If you want a fast 0-60, you need torque, and you need to hit it quickly. So, many factors go into determining a machine's performance, hopefully I explain it here a little more clearly.

I am not still confused. I am less confused. Thank you for this explanation and demo.
My teenager self would have loved a video like this! Keep it up 😄
This video explained horsepower better
👏👏👏👏👏👏👏👏
Good explanation, the summary is all I need HP = torque x speed…
But I still need some explanation on elephant power… cow power and water buffalo power… 😊
Torque
Yep still confused😭🤣
Tell me that small cage circuits @wissamseif .

I'm currently in third year of petroleum engineering (yes I know your take on it and really hope it will prove wrong 😂).
Out of all the courses so far, machine elements was my favourite (kinda regretted I didn't choose mechanical eng.). I did well on it, but now I really have a clearer grasp on the real meaning of torque and power so thanks a lot for this concise explanation. And keep doing the vids, they are awesome 👍
Are you not able to switch your major?
Well explained 👏 👌 💯, now can you please explain entropy like this 😁
“your probably still confused…” 😂 that had me. As yes, still a little bit!
Torque at wheels is important, torque at crankshaft is largely irrelevant in theoretical discussions like this since gearing makes up difference. Two engines with XXX HP have same potential to make torque at wheels, I don't care if one has 2000 ft lbs and the other has 300 ft lbs, HP is all that matters. Now there are some practical nuances with engine longevity, heat, power transfer, etc
It's torque vs power, or lbf ft (Nm) vs horsepower. You're mixing up units and physical quantities here.
Also power does not equal torque times speed but is merely proportional to it.
Yea I’m aware that HP is a specific unit of power. Torque vs HP is such a common search that obviously that was going to be the topic here. Could’ve added a formula or two, sure
@@WissamSeif I guess id like to have seen you point out that even though you didn't change the motor, you changed the power output of that motor when you changed the gear. The faster gear forces the motor to operate at a slower rpm at the same speed. Thus, it is not just torque at the wheels that was reduced, but power as well.
Also, your car examples at the end, I would expect a 4000lb car to accelerate faster than a 7000 lb truck with the same horsepower. Power is work with respect to time. Moving the truck requires more work, therefore requires more time. And then the electric vs gas, I'm sure there is still some advantage to the electric, but what you really showed is that an AWD has far more traction than an RWD. And we already knew that
Very fun explanation. Liked the exaggerated expressions while lifting the desk lol
This is easily the most simple and best explanation in the top 10 TY algorithms. 👍
1:33 car brought its passenger along with it.... was it a cockroach..?? 😂😂
Lol when he said I'm still confused... yes sir I am still confused but good video
Well done bro. You explained it better than any of my ME professors and other content creators!
I’m 31 & trying to recapture my youth by learning the things I should’ve learned if I had an active father in my life, so thank you. A grade school kids could probably get this information but since I missed out on it my old a** is grateful lol
Hi Wissam, could you please make a video on truss analysis? (Method of Joints and Method of Sections)
Clear and to the point. Great.
I also enjoyed the errant wheel taking off to do its own thing.
Great video. i did a little project like this back when i took Mechanism but i couldn't find a gear to reduce the speed and at the end i used Arduino to make it work.
Well great explanation 👏🙇♂️
Would you choose a motorcycle that put's out 128 horsepower @ 12,000 rpms with 59 ft lbs of torque @ 9500 rpms and weighs 414 lbs (with a 765 cc engine) or would you choose a motorcycle that puts out 117 horsepower @ 10,000 rpms with 68.5 ft lbs of torque @ 7000 rpms and weighs 228 lbs (with an 890 cc engine)? The 765 cc engine is geared to be at 5,500 rpms @ 65 mph in top gear and the 890 cc engine is geared to be at 4,400 rpms @ 65 mph in top gear. Imagine that the both bikes would be loaded down with 235 lbs with rider and gear. Incidentally, the larger 890 cc is considerably more fuel efficient by at least 6 mpg.
I'm still confused LOL! But still most entertaining video on the subject I've seen yet. Thanks!
Your definition of power is specific to that which is generated by a torque. In general, power is the amount of energy transferred or converted per unit time, regardless of the method used to transfer the energy (e.g. a shearing force). To determine the number of Watts per Horsepower, simply take the year Columbus discovered America (after the Vikings) and divide by two. 1492 / 2 = 746. Just a happy coincidence.
Once i said to my friend while I was fixing his bike "this is a Torquing wrench okay"? and we couldent stop laughing once he pointed out how it sounds.
Does speed come from the number or rotations per second?
@@WissamSeif Thanks :- )
I like your videos 🤩🤩
I am currently taking dynamics, this stuff is awesome
Hi Wissam! I have a question that I’ve been asking myself for a while. I’m between studying electromechanical or mechanical engineer but I hear people say to choose one of the big4 so I don’t if choosing electromechanical isn’t such a good choice as mechanical would be
When you are trying to have pee with the morning wood. As you push it down, your heels come off the ground. That’s torque!
torque is get off power, HP is capacity before stalling.
@wissamseif can we have both high torque and high horse power
is i true that if I say we need more torque to accelerate and more horsepower for higher speed?
I think horsepower and torque are both needed for acceleration. You can deliver whatever required torque or speed that you need at your wheels with your gearing. Teslas and EV's have great acceleration b/c electric motors hit their peak torque immediately. That's another aspect; a 300 HP combustion engine is it's peak power. It takes time to reach it, whereas an EV hits its maximum torque immediately, and thus has more torque and HP off the get-go. At higher speeds, HP becomes more important.
On set gear yes + more hp at certain rpm cos gear ratio is fix on 1 gear so even with 1000 hp but at 1000 rpm in scooter with 1 gear 1000 rpm at 10 km/h it dont achieve let say 20 km/h on this gear depedn how rapidly power drop down 👌🏻now than 👉🏻jadea G5 120 nm 3 hp 100 kg 0-40 km/h /0-25 mph in 6 sec watch from 2:30 min 👉🏻 m.ua-cam.com/video/E2xUoO5dptk/v-deo.html&pp=ygUJeWFkZWEgRzUg vs honda dylan 150 only 14,2 nm but 15,5 hp +clutch and cvt 140 kg rider weight in both case probably similar 80-90 kg 0-40 km/h in 3,0 sec 👉🏻 m.ua-cam.com/video/JoMRbPpd__g/v-deo.html so such vehicle with 8,5 timess less max crank engine torq which alos is heavier with rider on it accelerate 2 times faster from 0-40 km/h thanks much higher power + centrifugal clutch and good gead gearing cvt which transfer those power to the wheel also cvt have huge drove train losess comapre to dorect hub motor in wheel jadea G5 just jadea have so small power that dylan 150 still despatie haveing mich biger drive train loses put more power to the wheel now than which vehicle generate more torq at drive wheel axis ? its honda dylan 150 it delivery waay higher drive wheel axis torq 👌🏻 it must if drive wheel have simialr or even biger radious if it accelerate faster and is heavoer otherwise it would not accelerate fadter 👌🏻but this biger drive wheel axis torq is delivered from much higher engine power 😁👌🏻 torq at engine and torq at wheel despite subcribe the same phenomenom are not at the same level excepet at gear ratio 1:1 in most at 4 gear it happen not including drive trwin losess etc for achieve max sped limited be all putside resist you need peak power rpm for achieve max posible acceleration at set speed you ned peak power rpm for achieve max acceleration at set GEAR now you needpeak tprque engine rpm 👌🏻 torque is leverage dependend thats why at set gear push strongest cos Nm:m= force but power os speed dependend thats why it push strongest at set speed cos power:speed = fprce at end of the day for daily riding you need (or atleast most people including me )as much torq as posible for nice pickup from low rpm without needs to reduce gear constantly and rev engine high but …for race this is irrelevant in race is only one rule assuming grip is enough you hold one peak power rpm or lost race 😎👌🏻
I find this stuff really interesting. Do you think someone could get a job as a mechanical engineer with a physics degree? (BS)
@@WissamSeif Mechanics, thermodynamics and statistical mechanics, quantum physics, and wave optics were some of the classes we took. It was an applied physics degree, we even used MATLAB which is popular in mechanical engineering right?
@wissamseif what are that small gadge in silver linked to the dc wires
I needed to know this after seeing the word torque in NFS
Wow Wissam you have summarized it in a very simple way!
I am a third year Mechanical student and I am ashamed to say that I was lacking these info, thank you Wissam 🙂🙂
Thanks. I have long felt that I didn’t have a good grasp on the torque vs horsepower issue. As I was watching/listening to your video I kind of crystallized fie me (I think). Let’s see:
Horsepower determines how fast you can go (eventually). Torque determines how long it will take to get to some speed. ??? So horsepower tells us about speed but torque tells us about quickness. ???
Yes. Torque is acceleration, horsepower is top speed (both depending on gearing)
nope, power is everything, torque tells us very little about performance
I understand thx
Strange. Still confused .The motor in both models have the same torque and horsepower. The torque and horse power has been modified with gears. Saying two vehicles have different powers should not be measured anywhere but at the crank shaft. What you do with that power afterwards is up to gearing. Only motor design really changes horse power and torque?
They shouldn't have different power since it's the same motor for both. Gearing will change the torque and speed at the wheels. So yes you're right, I should've said this vehicle has more torque at the WHEELS than this one because of the different gearing.
Video is faulty like most of the videos on topic. If a cars "gets of the line faster" than the other, it is because its power to weight ratio is higher, with no other option possible. Simply by definition of power. These electric motors have a power curve, and power increases with motor's speed to some point. By adding a reduction gear, we change a ratio between car's speed and its motor speed. The motor now, as we say, works faster (which literally means developing more power) at any speed range of the car, so it accelerates faster.
bro the cockroach be like:help meeee 😣
I'm less confused now :-)
Thanks.

still confuse 😅
But how this relates to race cars, if a race is under torqued what’s gonna go abnormal will it take longer to reach top speed or what?
yes. Torque will help acceleration depending on gearing.

Hehehe.....car go vroom..vroom.
Horsepower is the rate of using torque to produce motion. Torque is just a force, you can have 1000 lb/ft of torque with zero rpm, and that will have zero horsepower.
torque is not linear force 🤮👎🏻100 hp 1 nm at whell at 10 km/h generate 100 times more contact path force at drive whell than 1 hp 100000 nm at whell at 10 km/h 😎 power at set speed if FORCE 👍🏻😎you will stop usuing hand 1 hp 100000 nm at whell at 10 km/h with easy in comapre to 100 hp at 1 nm at 10 km/h whell spin be imposible basically it ripp off ypu hand 👌🏻if ypu try stop this whell with such power level and torq level vs 1 hp at 100000 nm at 10 km/h be probabaly posiible to stop cos from 1 hp at 10 km/h be geenrwted around 27 kilograms force thpugh ypu must also includend inertia pf rotstion whell so depend how heavy asf it is build it can be easier or harder to do but still posibble at such setup vs 100 hp 1 nm at 10 km/h the same whellwill required 2,7 tons of force at tire circle to stoop it beside ypu must also included add again its rotstional inertia energy /momentum but you can feg match speed whelll be ypur hand catch it and than while rotate with it try to exert ypur force and try to slowwww it down and finally stop it what with 100 hp and 1 nm at whelll at 10 km/h be absolutely imposibble to do cos 2,7 tons force is quoet alot i quees 👌🏻😉 but 27 kg force from 1 hp at 10 km/h at 100000 nm yea easy 🤭👌🏻even small women be ise proper technique which im wusbcribe be able to stop this whell absolutely 👌🏻 so no torque is not linear force it is leverage dependendd and power is speed depended 👌🏻1000 hp 250 nm engine beat with easy in 1/4 mille drag race uphilll let say 5 degreee incline so more than avg viaduct 👌🏻 pulll with 100 tons on trailer somethin like 250 hp 10000 nm alos with 100 tons on trailer up the same hill both at perfect gearing so very individual choicen precise for specified power characteristic graph gearing cos power:speed = FORCE 👌🏻
@@mociczyczkiThe numbers you gave are irrelevant if you don't tell where they are measured. Power is torque x speed. To have 100 hp with 1 nm you would need 700 000 rpm. To have 1 hp with 100 000 nm you would need 0.07 rpm. But you said that in both cases the speed is 10 km/h. That would be impossible because you said that the torque is measured at the wheel so the rpm would also be for the wheel. The only thing that would explain it is if there was 10 000 000x difference in the diameter of the wheel or the hp you gave is the specification of the engine and not the actual power it was producing at that moment
@@laserdiode 100hp/1nm vs 1 hp/100000 nm at whell at whell speed 10 km/h for both like im write 👌🏻🤷🏻♂️

Thanks a lot. I like the last part, about still being confused.
horsepower is how fast you hit a billboard. torque is how far you drag it.
😂😂😂🤣
The most incorrect analogy possible.
Nope. Horsepower is the rate of using torque to produce motion. Torque is just a force, you can have 1000 lb/ft of torque with zero rpm, and that will have zero horsepower.
How far you drag the billboard is still power, because power is force times DISTANCE over time.
Ok boomer
That’s wrong asf
Very good :-) thanks
Great video… Really explained it well… Well done

torque is leverage dependend from less torq if arm lever be enough shorter output force be higher 👌🏻 power is speeddependend the same power at lower speed mean more output force 👌🏻 thats why at set gear biger accelerstion be at max torq aprpm cos speed is diffrent than at the same gear at max power rpm but at set speed and diffrent gear better accelerstion be at max power thats why feg honda cb 500 pc26 with rider 280 kg 57 hp 9500 rpm 47 nm 8000 rpm accelerate to 140 km/h in 10,0 sec rider weight 90 kg 👉🏻 m.ua-cam.com/video/imk3BtPIW6U/v-deo.html vs feg royal enfield continental 650 gt 280 kg with rider 60 kg 47 hp 7250 rpm 53 nm 5250 rpm need almost 13 sec / accelerste to 140 km/h in 12,7 sec 👉🏻 m.ua-cam.com/video/9jWRoS_pd7E/v-deo.html&pp=ygUqcm95YWwgZW5maWVsZCBjb250aW5lbnRhbCBndCBhY2NlbGVyYXRpb24g 👌🏻 👉🏻power at perfect gearing and clutch setup win race 🌪️👌🏻 but alot torq down low on rpm is good for daily riding for most driver including me 👌🏻 i would rather have in cb 500 55 nm at 5000 rpm and 50 hp at 8000 rpm instead of stock setup 47 nm at 8000 rpm and 57 hp at 9500 rpm for daily riding 😁👌🏻but in race me version setup dont win cos weaker topend 🤷🏻♂️ but from idle all the way to like 7000 rpm be much stronger than stock setup and more pleasure to rode for 80-90% of avg rider on road 😎 everything change on track under fast rider where stock 57 hp cb smoked me 50 hp woth better lowend hipothetical version 👍🏻

Hey Wissam, what’s up. Love this video just like everything else you put out. I’m a first year engineering student and I plan on doing mechanical engineering after I transfer from my local community college.
Hey, so I wanted to talk to you about something that might sound a little dumb. 😅 For a while I’ve been thinking about getting a dual degree in mechanical engineering and mathematics or at least a math minor from the four year school i plan on transferring to. The reason why is that at my school mechanical engineers take calculus 1-3, differential equations and numerical analysis which is already a great background in mathematics but we aren’t required to take things like linear algebra or partial differential equations - things that I’ve heard are good to have a background in for mechanical engineering. Another reason why I’ve thought about this is that I plan on going into aerospace engineering (via a masters program) and I’ve heard it’s one of the most math heavy industries in engineering. I just thought maybe a math degree would greatly prepare me for an industry like this because I’ve heard it can be really challenging. My ultimate goal is to work as an aerospace structural engineer at NASA (knock on wood). 😅
If one of the first things you were to mention is “it’s going to cost more money, maybe just stick to your main major,” that is something I’ve thought about but in my [U.S.] state they help to pay for college if you go down the “college path” in high school and i also plan on joining my state’s national guard and here you get 100% tuition exemption. I’ve honestly been planning out this whole dual degree for sometime and it does seem possible to be able to pull this off with just an extra year of school.
I don’t know. I just wanted your feedback since you currently work in the aerospace industry. Anyone else who sees this feel free to comment. I’m open to feedback. 🙏
Maybe these questions will help you out to understand the topic and stop spreading misinformation?
1. If you feel torque then put a larger wheel on the axis and try to stop it. Why it is easier now despite the same torque?
2. If you need lots of torque to get something moving, why a man can tow a cargo plane, or a locomotive with dozens of carts? Check some videos on YT.
3. If you can move a light load really fast or a heavy load slower and put out the same power in both cases, then why two vehicles can have the same engine horsepower but have completely different functions? On top of that, 5 seconds earlier you showed yourself how gearing works.
4. Uncomfortable info for you here: if an electric car outperforms a gasoline of the similar specs because it reaches its peak torque faster, why the truck's specs engine is not installed into a race car? Not only it has a double amount of torque but it also reaches it faster.
5. If you need torque to move, then what is force/thrust?
6. If horsepower is torque x speed then what is power?
7. If horsepower is how fast you can move that load, then why you need torque for acceleration?
8. If horsepower is important, why there is no a single word about how exactly it's important in the video?
@@WissamSeif @Wissam Seif bad answers, looks like I have to sort it out by myself.
1. You can't feel torque, it is physically non-existent.
2. Or you don't "need lots of torque to get something moving". Or both.
3. You explained power as force times speed. And how gearing changes the balance between them. This means gearbox doesn't need any specific amount of input torque for a vehicle to perform any kind of job.
4. So when it is about electric vs ICE of the same power, electric wins because its torque is reached faster, and when it comes to diesel and gasoline, diesel does not dominate because "it's not just about torque and horsepower".
"ICE doesn't hit its peak torque until it's near its max rpm". Ever seen a torque graph of ICE?
5. True that a car needs to overcome some extra static friction from a stand still start. Now get back to your "power is light load faster or higher load slower". 2+2= you need more power if you want to overcome more at/from the same speed.
6. Horsepower is a measurement of power. You mess already at the stage of the basics.
7. Explained in number 5
8. You didn't explain it well enough to yourself before the video was even made.
@@WissamSeif you just don't care in general, why do I have to treat you well? You don't even know the words' meanings and r trying to educate others.
@@IgorArkin dude have you ever taken a physics class? Don’t think so
@@IgorArkin torque is non existent? Are you stupid?

thanks for the video i was looking for that exactly
Horsepower spins the rotisserie. Torque cooks the meat.
Best explanation I’ve ever seen! 👍
Torque is the strength that helps you start moving and carry heavy things.
Horsepower is like speed and endurance that helps you keep going fast for a long time.
Wrong and stupid analogies
@@IgorArkin How's it wrong?
@@ricardomilos1784 absolutely. Just read what power and torque is. Or let's start with you proving your point with basic physics and you will see it is not possible in the process. Also violates any logic.
@@IgorArkin OK professor, can you explain it in simple terms? I don't feel like reading the information about what torque and horsepower are.
@@ricardomilos1784 easily.
Power is acceleration x speed with a given mass.
With the same power output, the slower the speed the better acceleration and vice versa.
You trade between acceleration and speed with a gearbox.
Torque is not related with performance because it can exist without displacement, and when displacement starts to occur it is described with power.
Loved this vid!!
Nice video. If only i could like it twice. Lol thanks
Remember when similar video (but less well done) where the comments was filled by people wrongly saying why torque matters but horsepower doesn't... yeah they really didn't understand it even after that video.
But atleast with this one its pretty obvious as you say "horsepower is how often torque is applied (as a matter of work done)". Good job.
you need hp for 0-60 torque is irrelevant 👌🏻 feg ola s1 pro 58 nm 8 hp weight 100 kg vs yamaha r15 14 nm 18 hp 140 kg like you see electric with more torq is smoked be combustion on acceleration 🤷🏻♂️ m.ua-cam.com/video/CUzfubAUD6U/v-deo.html hp is what move stuff torq is 💩🥳
@@mociczyczki this engineer should have provided a formula that features torque and acceleration, which doesn't exist. Instead, he is thinking up that torque is force and vuila: "horsepower is speed torque is acceleration". Classic.
@@IgorArkin hehe 😂 yea power is speed tprque is acceleration 🫣
