I'm taking Physics 101 right now. It's so nice to have these videos to complement what I'm studying and strengthen my conceptual understanding...and it's free. I think a large part of our exhorbitant university fees in the U.S. is not really going towards quality of instruction rather than maintenance of the university - it's buildings, staff, administration, marketing and sports teams...
@Amy Pwyll Good luck! This video just scratches the surface on a few of the topics you will be learning about. If I can offer one tip now, it's to become really good at geometry before taking statics.
+Amy Pwyll, Mainly triangles, but both. As you become more educated in math and physics you will see how they actually go hand in hand. If you follow Dr. James Tanton's channel he mentions in a couple videos that trigonometry should really be called circle-ometry. Might be a good place to start if your looking for some pre-statics material.
Lol, tell me about it. My professor barely explains the basics and give us hard homework problems that require a more in-depth understanding of the topic.
Using this for my high school physics project on bridges. Never had statics, so was a good introduction and gave me what I needed for background information on factors to consider when building bridges.
I just learned about the young modulus and the elastic, plastic and fracture points on uni last semester, it is truly a very interesting subject to study
It's only at this point in my education that I realized this video covers material from at least four different classes, statics, fluid mechanics, materials, and mechanics of materials
Since the ladder is in equilibrium, the direction of the total force from the floor is not and cannot be exactly on the line of the ladder. To be more precise the line of the force from the floor has to pass through the point the line of the weight and the line of the force from the wall intersect. If anyone wants any further explanation just ask.
I have completly missed out on "Crash Course Physics". How "deep" into statics and mechanics will will you be going? I mean there are a lot to cover. Anyways i find this great and ill be sure to watch the earlier episodes too ^^
This video is great. Makes me more scared for my intro to mechanics and engineering class. I really need to study more. Thank you guys for the hard work!!
Are there any structural engineers, civil engineers, architects or architectural technologist who have just watched this and think, damn my physics lessons at college/university were never this dry.
I usually fell asleep in Statics, so I can't remember. The teacher would have gotten more upset, but I was aceing the class. She avoided sines and cosines.
A whole semester of this stuff. But moment instead of torque. I had a professor said to me and the class that moments are for statics, torque is for dynamics. Same mathematical definition though.
As a chem E, I was always curious about statics (civil engineering). Turns out I already learned all these concepts in my chemE classes and physics.There really *is* overlap. Who woulda thunk it?
you know, i think the components of statics should have their own episodes. As an engineering student, i love physics. but no one gets ALL of that in just 10 minutes.
Conceptually, (I think) it makes more sense to say that we are taking the perpendicular component of a force when calculating torque, not the perpendicular distance to that force. The mathematics works out the same either way. Is there some insight I'm missing that one gains from thinking about it as a perpendicular distance?
I am wondering the same. I see the relation being : T = F*r*sin(theta), where r*sin(theta) = distance but this doesn't seem as intuitive as finding the perpendicular component of the force relative to the ladder. Did you come to understand it?
Great video, A bit more to learn than I am willing to watch several times and take notes. I don't like math, but it's nice that it is there for people wanting to learn.
Brevity... plus, the newer generation is so used to it that I doubt it even registers. I'm getting used to seeing them everywhere... and I certainly didn't notice until you said something.
This stuff you definitely have to stop the vid and check the calculations now and then, just to be sure. Other CC courses I can just soak it up at normal speed but not this. And I used to know this stuff by heart. Summarising statics in 9 minutes? Amazing. Fluids next. I'm hoping that being a fluid dynamicist herself she will yield to temptation and go deeply into it. BTW, nice to see the Feynman Lectures on her desk.
Well picking the Boltons to fall from a high bridge to their doom would indicate that their status amongst fans for their past deeds would be perfect choice. Other words, they were terrible, they meet terrible end.
Omg thank you, my engineering school is soo boring, it makes me lose my interest in the subject.. but these videos are what keep me interested in this..
I'm a painter and I feel I should tell you that that ladder is in a dangerous position. 1 foot away per 4 foot rise. Otherwise you run the risk of feeling all that potential energy when your ladder drops from under you.
Very observant, now you are doing engineering analysis. The Three, Four, Five triangle is famous because... it makes Pythagorean theorem easier to do without a calculator. Therefore: 1) we can concentrate on the theory and the application instead of the math 2) Then we analyze the problem for design considerations. In this case, we can apply Young's modulus and, as you noted, consider the friction forces that prevent the ladder from sliding down the wall.

That moment when your exam is literally in 8 hours.
I hope you passed! I have one in 4 hours
I got one in two days, spooky times
I got 20 minutes. Wish me luck
@@nathanielstein8904 I hope Allah swt gives you success
I've once taken a full semester course learning Satics. And I am learning it all in a 10min video...
Yeah, this covers maybe chapter 1-2 of Hibbeler, good luck with that one.
Gotta love statics class. I think it covers even less than that

Plus it skipped stress/strain diagram, poisson, dotP, vectP, etc.
sorry, i couldn't really focus from the tears in my eyes bc i don't want to take this class
Lol, tell me about it. My professor barely explains the basics and give us hard homework problems that require a more in-depth understanding of the topic.
@@Johnnyy832 same
@@JasonpreetMann same. I thought this video would give information lol
tell me about itt

Gotta love those satics
nooo! I was litterally going to write the same thing
._______________________________________________________.
what is satics?...pls tell me .I am a dumbass.I didn't get it
@@shefatabassum5807 it's properties of matter.

Man, all the Game of thrones references. The twins, the Bolton banners, the book. Freaking awesome!
Man you wouldn't believe how much help a simple color-coding could give.
Great video
my understanding stopped at about 10 seconds, but my interest is still growing :D
I really love CC! Once you understand the video you understood everything! But understanding the video is completely another case ...
Even I learned something, and I've had two years of Mechanical Engineering courses. Don't remember Bulk Modulus.
"Inherent slide-i-ness" I love it.
I can't understand what you are .....tourqueing about.
That was really.... forced.
give me the bullet
BOOM!
CrashCourse woah! CC itself!
Hehe :D
-Nick J.
aww, the satics. an objects ability to sit down.
Fluid mechanics coming up! How exciting.
I love satics
I love how they talk about soo many topics at the same time like Hookes Law, Pressure and Equilibrium
so simple and so understandable...... seriously u guys are the best... I always prefer crash course for learning

That's the Twins/Crossing from Game of thrones......
Good to see Crash Course pledges to the true Warden of the North, Lord Roose Bolton.
He's been dead for seven episodes now. Sorry. Spoiler.
***** He is no dead in the book... crys and flays self
You've just given me a spoiler...........
This is sooo useful...gr8 effort, especially easy to understand
I have completly missed out on "Crash Course Physics". How "deep" into statics and mechanics will will you be going? I mean there are a lot to cover.
Anyways i find this great and ill be sure to watch the earlier episodes too ^^
4:31 Change your banners!! The Starks rule the north again!!
first time watching one of these. really like the formula highlighting method and color coordination with the diagram
I love how thought cafe casually included a game of thrones reference to a flayed man. No complaints:)
For those having problems understanding, it really helps to replay the video throughout the week.
Gotta love those Bolton flags.
Anyone found that Game of Thrones reference? Flag?
I caught it, but... why the BOLTON banners? Why those in particular?
*****
the latest episode was all about boltons
Did you see those castles at the beginning? Those are the Twins.
This video is great. Makes me more scared for my intro to mechanics and engineering class. I really need to study more. Thank you guys for the hard work!!
Am I the only one that has to rewind every 30 seconds to let this stuff sink in?
Looking at this the summer before the class. Omg I cant wait. :D
Are there any structural engineers, civil engineers, architects or architectural technologist who have just watched this and think, damn my physics lessons at college/university were never this dry.
Im starting my civil major next year and im pretty sure my statics class will be way more boring
I usually fell asleep in Statics, so I can't remember. The teacher would have gotten more upset, but I was aceing the class. She avoided sines and cosines.
+Ross Parlette "She" means here, not back in college.
No, the lectures on statics were worse.
Statistics classes were the driest classes of Uni and had the least practical examples and the worst teacher.
A whole semester of this stuff. But moment instead of torque. I had a professor said to me and the class that moments are for statics, torque is for dynamics. Same mathematical definition though.
Thank you Crash Course, you're my only hope

good 'ole satics
you know, i think the components of statics should have their own episodes. As an engineering student, i love physics. but no one gets ALL of that in just 10 minutes.
This CC alongside with History CC are my favourites. Keep them comming please! >:3
excellent video
You made that ladder problem a lot more confusing then it needed to be
Сопромат, наконец что-то что я не учил в школе. Finally something I didn't study in school
I wish this video was out when I took my statics class lol really good video
These are the bests
8 hours before my exam. Let's go Crash Course!
Brings back memories. Good times, good times
i love this channel

exactly
Ahhh, this course brings back my engineering days and doing problems on engineering paper.
I Love The Ladder
Fantastic video
A new CC Physics: time to crank the speed up to 1.5 . . . and comment while the video is running.
I love this awesome physic teacher !
The flayed man! I see your bridge GoT references. Nice.
I like her voice. It's pleasing to the ear.
Great video, A bit more to learn than I am willing to watch several times and take notes. I don't like math, but it's nice that it is there for people wanting to learn.
the flayed man of Bolton on the bridge, the twins. Way to make me sad guys
2 hours before my final quiz. Let's go crash course!
frey twins & boltons flayed man ^^
i love the game of thrones references
Why do you jumpcut ALL gaps between sentences?
It makes all the information almost impossible to comprehend.....I totally agree.
Brevity... plus, the newer generation is so used to it that I doubt it even registers. I'm getting used to seeing them everywhere... and I certainly didn't notice until you said something.
+Mark G i don't have a problem with that ...
The normal 1-2 second pause is time to contemplate and understand the new information. This is how my mind works.
.
I can and I do use pause. Left arrow backs up time 5 seconds.
another epic episode
I like the new graphics
Crash Course got me into med school. GOD BLESS.
Thankyou
Her accent makes this video sound a little Dr. Seuss with all the force floor and wall
Imagine Shini having to say it over and over. She was a trooper that day!
-Nick J.
Looking forward to the outtakes :)
Haha I was thinking that exact same thing. I flippin loved Dr.Seuss way back when I was a young'n.
Requesting crash course aviation :P
i have a physics exam tomorrow and im trying to learn everything from a 10 minute video omg someone save me lol
so - did you pass?
Seriously you’re making Physics easier 😭💓
It lessens my stress for upcoming events 😄😄
Best intro in my opinion, wish it went longer!

Object in equilibrium
Fnet = 0 & Tnet = 0
Calculate forces and torques
Object deformation
Tensile( stretch object out), compressive and shear (sliding)
Pressure
I'm so happy these videos exist! This is how I study for college finals.
Satics are the best!!
you made statics so fun , thanks
grreat video. excited for more physics on crash course
I got a 92 in statics back in college 10 years ago. Im taking a professional engineering exam in a few months gotta brush up my skills
Am I the only one confused by the Bolton banners at the sides of the bridge?
Just a reference to a popular show. Doesn't have anything specifically to do with statics, probably.
Sure it's a reference but ... there are a lot of houses to choose from. House Bolton is a somewhat odd choice.
Well picking the Boltons to fall from a high bridge to their doom would indicate that their status amongst fans for their past deeds would be perfect choice. Other words, they were terrible, they meet terrible end.
Omg thank you, my engineering school is soo boring, it makes me lose my interest in the subject.. but these videos are what keep me interested in this..
I found this quite helpful.
Torque? Not in Canada. We call them moments. I'm in my third year of engineering and only in dynamics has it ever been referred to as "Torque".
SATICS THE EDGEHODGE!!
exam tomorrow morning, lets go crash course
Does anyone else see the bridge looks just like the Twins from Game of Thrones?? :P
Honestly Statics was a fun class. It's dynamics where the poop hits the fan 😂
I have a BA in physics and know virtually nothing about this topic. Nice episode!
Thank you for the video
Thank you for the video!! It was so well made and I understood everything.
I see that three-eyed raven in the tree at 4:14.... There are too many Game of Thrones references to count in this episode
that bridge really looked like The Twins (the seat of house Frey in Game of Thrones)
Thank you for yet another lesson on my favourite subject!
love me some satics
I learned more in these 9 minutes than I did throughout the 4 month course at school....

Great show! Really nice way to link the different stresses!
After seeing the "Game of Thrones" book, it seems what I thought Bolton's banner is actually the Bolton's
