Thanks for sharing, I've just started in the automotive industry and needed a basic understanding of torque as it applies to the vehicles I'm dealing with. As a total layman I found this very informative. Cheers from New Zealand =)
Great use of visual aids! I think it'd be helpful if you explained why the 200g was 2N. But a quick google search helped me understand that. Thanks for putting this up!
Professor I found your lecture total by accident. But as an adult working on building a small business, I thought it to be very illuminating and helpful. I have one question. If you have an object, like a 50 gallon barrel on its side, how would you calculate the force the force as a sole value without torque? Thank you Alan
no. the units for Force are newtons, kg*m/s^2. therefore, u would convert 200g to .2kg. then u would say the force of the block on the ruler = mg. mass times gravity. F = ma => mg = ma => g = a. therefore, mg = .2*10 => F of the block on the ruler = 2N.
because 5250 rpm needs to intersect torque and horsepower power figures so the engine rotation speed causes power to increase do to speed increasing because more work is being done in a give amount of time. torque is a mathematical equation.
considering if the force applied in 90 degree angle this formula is correct, otherwise it requires angular acceleration since we have a force that works though rotation axis
May I assume that the beam will be in the same position, for instance, at a certain inclination of some degrees, if I put two equal masses at the same distance of the pivot ? Or it will rotate to the horizontal position ? In this case, why it turns to zero inclination, if I put two equal forces? Shouldn't it keep at the same position, considering the fact that the beam are subject to the same torque?? Thanks
wow great video i don't even do physics but i was curious about the subject and i must say you fed this info. to us like baby feed (my opinion at least) maybe i should have taken u[ the subject.

Greetings video maker, I appreciate your efforts but I am confused whether my book is wrong or you are wrong or you and my book are right but I am wrong because my physics book says torque is "THE TURNING EFFECT OF A FORCE ABOUT A PIVOT " but you are saying that the torque is the force itself but the book says that the turning "EFFECT" of a force is torque, so please clarify.
Torque is a concept, not an independent force. Any kinetic force not applied in the centre of rotation with the result of the object rotating is torque.
torque is a vector, it has both magnitude and direction. This guy doesn't explain that the angle between the force and radius (just a distance between where the force is applied and the axis/point of rotation is 90 degrees or pi/2 radians. the magnitude of torque equals r times f times sin of the angle between the force and radius vectors. in this case theta= 90 degrees or pi/2 radians, which means sin of the angel between the two vectors is equal to 1, if you refer to the unit circle, so the problem is very simple when the only force acting on an object at some r away from the center of rotation is a force perpendicular to the direction of the displacement in the radial direction (just the distance you are away from the center of rotation (the radius)). sin theta=1 so the torque becomes r times f. But what's the direction, since it is a vector? Learn how to use the "right hand rule" move the vectors tale to tale and move the r side of your hand towards the f, the direction of your thumb will show the direction of the torque. in the case of this problem the torques directed into his white board. if the same weight was on the opposite side with the same distance from the pivot, the torque would come out of the board. This is because we define counterclockwise rotational motion as positive change of angle and clockwise as being negative theta. Hope this helps, or at least makes you see the depth of your ignorance.
torque turk tark in india called arguments, so if you have better arguments then we can easily turned the opposition in diverted direction this tark is like torque, in arguments and in physical machines representation😝😝😝😝

Nice work. Thanks so much for helping myself and our 12 yr old son understand torque.
Watch in 1.25 or 1.5 speed. You're welcome. Good video by the way!
This really helped me understand Torque. Thank you. You are a good teacher.
Thank you for sharing your knowledge. I have grown mine.
you teach me in my 2nd language
but I understanding you more than my teacher in region language
now i got the actual concept of torque...👍 nice teaching
Great video! I with you were my high school physics teacher!
Thanks a lot ,, Helped me a lot as a slow understanding person
it was soo understanding video...thnxx
Great use of visual aids! I think it'd be helpful if you explained why the 200g was 2N. But a quick google search helped me understand that.
Thanks for putting this up!
Darcie Can you verify with me that F=2N is an approximation of Force =mass * acceleration = 0.2 * 9.81 m/s^2 = 1.962 N?
pussiestroker what's the units on the mass?
Darcie kg.
+Darcie how did you get to understand that. can you help me please
It's quite helpful. Thanks for you help !!
thanks sir it helped alot
nice video i understand everything thanks
great video thank you

good video!
fantastic...open my eyes!!!Thanks...
u r amazing...!!! i understood all of it ... i like that u talk slow i can take in all the info!!
This was really helpful. Thanks!
You are good!
Thanks for your videos man, teaching good ;)
Keep goin' !
Well explained. Good work...

this was very helpful. thank you!
was slow enough for a beginner like me, thank u
good video
many thanks,
good explaination, thank you.
Thanks!
Thank you :) That was very clear
Rosanella :)
really..amazing..! :* just understood in a moment!
because 5250 rpm needs to intersect torque and horsepower power figures so the engine rotation speed causes power to increase do to speed increasing because more work is being done in a give amount of time. torque is a mathematical equation.
and i want to ask a question.. if the torque is a rotational force, why in engines we use torque too.. is it because the crankshaft dials?
I was in your class!
The force in the example you gave, isn't it the mass times gravity. Kg•acceleration. Not just a mass?
considering if the force applied in 90 degree angle this formula is correct, otherwise it requires angular acceleration since we have a force that works though rotation axis
so u missed a bit trigonometry and that is a huge mislead for people!
exelant solution for torque
better than my physics professor
that a heart on his shirt?
May I assume that the beam will be in the same position, for instance, at a certain inclination of some degrees, if I put two equal masses at the same distance of the pivot ? Or it will rotate to the horizontal position ? In this case, why it turns to zero inclination, if I put two equal forces? Shouldn't it keep at the same position, considering the fact that the beam are subject to the same torque?? Thanks
thank you
thank you for helping me understand sir
Great teacher you are.. :) Thank yoU!
Good.
Thank you very much, keep it up.
very usefull video. Thank you very much!!!
sir,but cross product of two vectors is again a vector but you didn't talked about direction
Nice
Thanks that helped soooooooooo much!!
thanks for the video its nice.. the stick is in balance but the board is not.. :))
"its not accelerating in a circle" wow you are a genius.
wow great video i don't even do physics but i was curious about the subject and i must say you fed this info. to us like baby feed (my opinion at least) maybe i should have taken u[ the subject.
Great video but you’re in CA which is in the USA so please use SAE terminology ft/lbs etc....
great ! thanks
dont u need to change the 200g into Kg? or does that not matter?
excellent teaching
he did covert it into kg
Why did people give this video thumb downs?
Eddie Tong Because within any viewing population, there is going to be a percentage of people that are crazy, mongo, dullwitted or otherwise incapable of saying "thanks".
+Eddie Tong Because he must me teaching 12 year old children, and thus he is boring them to death and probably failing to deliver.
+Adam Waldorf yep, have 13 and this is pure shit, 0:05 wasnt listening any more uppss sorry soooo borring
+Captain Feni ikr, that's why...
because it is not 100% correct, so that is wrong!
thanks............

GOBBLE GOBBLE GOBBLE.... TURKEY BOY!!!!
no cross?
thanks you teacher :D
you didn't determine the important factor that is the direction of torque............

i thought torque was done using vector cross products
The formula is incorrect. Actual one is torque = force cross product radius, or torque = l F l * l r l * sin(angle)
They are both correct. your formula is a more in-depth equation used to find more specific questions/problems.
he is also talking about tangental forces, you are talking about something related, but not exactly the same

Thanks for this video. And you're quite attractive. Lol...
@coolasme05 F = m*a.. here a = g. He just rounded 9.8 up to 10. (and converted grams into kg)
hes so cute
Rotational Equili6rium 4:44

lol
but you definitely wont understand nothing about torque like here.........
you speak way too slow!
