Example of physical system = Formula 1 car and an Ashok Leyland truck, both have 500HP engine (lest say). But, F1 engine produces the 500HP at higher RPM and lower torque. But, Leyland engine produces 500HP at higher torque and lower RPM. Higher torque translates to higher load pulling capacity in vehicles. Whereas, higher RPM results in higher Km/Hr speed.

so, does the gearbox has an effect on it? or it's just the engine?
we r building Formula 1 car.. in our college

hello i am not a student of science though i wanted to know if i knew the rpm shall i have to calculate the torque ? my second question is if i used a motorized kite spool that diameter is 3 inch and rpm is 3000 then how much thread it can rewind in meter/s .
I am basically a B.Tech Mechanical Engineer from TKM Kollam, Kerala..also done Dip. in automobile engineering.
I just watched like four other videos that were confusing as heck. This was quick and clear, got it. Thanks!

Thank you.
have a look at our other videos too
Very clear and concise. Good example with the cardboard.
Dear Gurpreet,
Its about engines, there is a limited range of RPM for efficient ie: torque, when RPM increases the force of rotation reduces ie. torque reduces,, there will be various losses for the torque when RPM increases.

nice work sir, why i wrote like that is because almost 25 years i am on job but was not able to grasp this terms practically . especially torque because i am industrial electrical technician. theoretically i understood , but many people use it as if its like interchangeable .
First time to understand whats the torque .
Thanks
You did a good job
thnx a lot sir,instead of watching 1 hr video its better to watch ur videos and understand the concept ,it saves a lot of tym. EXCELLENT TEACHING....:)
Thank you, please watch our other videos too and rate us.
Thank you.
Thank you.
will upload a video on that, you can download our android app from Google play just search for Techtrixinfo.
Great. . .
We can understand Easily...
Congratzzzzzzz. . .
Thanks my brother. we are watching your videos in south Africa
It is nice to watch ur videos. you are clear in speech and directly touch the core of the subject, this saves the precious time of the students who want to learn from you. Thanks and keep going , I will tell others about your videos.
You have definitely cleared my confusion .....god bless you

Will definitely do that.
The design of pulley and bracket required by a small firm of contractors for the lifting of stone slabs during restoration work is shown in figure. The bracket is to rest on a plate grouted into an existing wall and is to be held in position by four wall bolts. The loads lifted will not exceed 11800 N and the lifting operations will be carried out by hand winch. The design employs simple welded construction, aiming at low production costs and early delivery to the firm.
Thanks for the comment.
that example really helpful to understand it so easily...thanx a lot...

Nice explanation. Will u please explain about what is displacement in Engine?
Great explanation with a real time example.
good explanation .. thank you
Yes its can be bust its complicated the, FIP (fuel injection pump) timings need to be changed and valve operation also need to be adjusted.

Well explained. Thumbs up !!!
used good example to explain......nice!!!!
Hi. You should mention that Torque multiplied by angular velocity (radians/sec) is the Power generated by an engine. Angular velocity is just another way of representing RPM. Each full rotation is 2xPi and Pi is 180 deg. IN a way angular velocity tells us the rotational speed per second. Since Power generated has a peak value, the combination of Torque an angular velocity gives an idea to the customer, what would be the 'pick-up' of a car from low speeds to high speeds
very nice explaination
Nice video . Can you please add video for torque calculation of chain hoist?
tks for giving this useful video
I think of all the torque vs horsepower explanation i have seen on youtube, this video and specially your pen in the cardboard technique explaines it the best. Thank you very much and keep up the good work.
true..that example worked

Very Good Keep It Up.
Great explanation 👌
Thanks. Your Video is very useful. Its possible can you explain, How to read performance curve for Motor? (Speed Vs Torque etc..)
Good.
rpm and torque are inversely proportional to each other.
Hey guys can you explain how engine torque are stored in flywheel and releasing that energy when clutch engages.
Super explanation bro 🤟🤟👏👏
Good explaination ty sir
Simple & good
nice one idea...................of this diffence
A very nice explanation. @TechTrixinfo.com I am doing a project on Hybrid Vehicles. Since I am new to the automotive field, I dont have much knowledge about the engine and stuffs but I am very curious to everything, right from the very basics, e.g. all the torque and speed relations, why cant an engine run negative, when to shift etc. Do you have a blog or some videos which could help me off with better understanding ?
Great definition about this two
super sir. i undrstand ur teach. very nice
nice videos bro, i want more videos related to construction equipment like wheel loaders, skidsteer, backhoe loaders etc
Tks its motivating..
Which bike would be better?
All other specification remains same only torque is as follows:
Bike A =12.8 N.m / 6,000 r/min (2 Valve)
Bike B=9.5N.m/9000 r/min (4 Valve)
As far as I understood, If the torque increases (Force) there would be more revolution, so how could if RPM increases the torque reduces? Please explain!
My Dear, Torque is inversely proportional to RPM. consider the selection of first gear in going up hill,the car can go up because of a high torque and notice the speed then, it is considerably slow.
Yes. to the point.
*RPM x torque = power (HP, watts, etc.)*
Using things like gears, you can "trade in" torque for RPM and vice versa.
When you run an engine unloaded, it is freewheeling and the RPM will rise and rise until friction becomes great enough counter-force to slow it down. Now your engine is running as fast as possible!
When it is going fast like that it is easy to slow it down more since there is little torque. By adding a load, say, one that will demands the same torque no matter the RPM, the engine will slow down and may even stall! As it slows, (decreasing RPM), the torque increases. Once it increases enough, it will drive the load at bogged-down RPM just fine!
Theoretically, you could use a motor from a drill to push a big truck up a hill, if you convert the speed of the motor into enough torque to overcome gravity. Of course, it would be very VERY *VERY* slow!!
If you want to consider something like friction, the torque needed to overcome it will _decrease_ with less RPM, and _increase_ with more RPMs. the relationship looks something like:
*RPM = torque x resistance (like friction).*
Power Max Unfortunately, engines, like any other power-delivering devices, engines do not deliver the same total amount of POWER to different loads.
Say, if you had the engine unloaded (parked in neutral) and you revved it up. 100% of the gas used is wasted since no work is being done. *lots of RPMs, times ZERO torque, means ZERO horsepower.*
Similarly, driving up a steep hill in the highest gear would cause the RPM to drop to ZERO, and stop the engine. Thats because your transmission is tring to convert torque into RPM on the wheels. By doing so, the stick shift loads the engine down too hard and it cannot keep up. *So at very low RPM, you do not get much power to the wheels*.
These concepts I am sure are very difficult to grab at first, and making matters worse, calculus is often needed to express a lot of the relationships and all. I could also be wrong on my understandings, as I simply made RPM analogous to electrical voltage, torque analogous to electrical current, and horsepower analogous to watts. Also, the resistive load, is counterintuitively analogous electrical conductivity, not electrical resistance, but the opposite. (a short circuit is considered a low resistance in a bad place, while "shorting" the motor I would call high resistance since the motor is bogged down.
When RPM increases, Torque reduces. Its not because of friction. For same power, angular velocity (rad/s = 60/6.28 rpm) is inversely proportional to Torque. (P=T X w).
good sir
nice information
very nice ,he told them clearly i understood easily ,can you explain the same what is bhp

Sry i didn't get your question, can you be more detail.
could i trust the parking brakes in parking my car on a steep road
Thanks for the short and sweet session :) . This video seems to break in the middle of the session. As in it seems be skipping few words in between the session.
Thank you!
U clarified simply..tuns bro
Thank you/
Thank you.
Please refer about us to your friends also.

thnk you bro....
Very simple definition but most valuable video. Keep up good job!
Great Vid!!
Thanks for this bro . Why dont you make a video on whole vehical dynamics
Hey, thanks! Great video.
அருமை... மிக்க நன்றி... ♥
its nice bro.....please post on BHP vs TORQUE
Thanx.
great help pay lagu sir ji AASHIRWAAD dijiye !
I am sorry Sir, but Torque does not need revolutions at all. You can have a Stationary Torque as Torque is Force multiplied by Distance and there is no time involved the unit of Torque does not contain time it is a static situation really. The fact that an object can rotate due to torque well that is consequential of the application of Torque. but Torque can exist statically so rotating the cardboard when you meant to explain torque was totally wrong, you could have shown torque on the cardboard without rotating it, When yo explain do not combine two thinks at one, take Torque on its own first without rotation but static, All the best.
thanx bro !!
is there any way to increase the rpm of engine? i have a kinetic honda 100cc engine and want to use it as ultra light aircraft engine..but it needs to have more rpm
How do you prove full torque at under 2rpm over a series of velocities averaging 45 miles per hour including stand stills?
Can you explain difference btw torque and power (taking an example of a car)?
Yes, but it helps us to have a better life, for more updates join us on face book @techtrixinfo
if i want a motor to lift an object weighting 10 kg for example, what kind of motor do i need and how can i calculate it, thanks.
What is the formulae for torque or force require to operate 2 kw electricity to produce electricity
Thank for explanation
thanks man
so nice
Explained well
Thank you..
thanks
