Physics, Net Torque (5 of 13) Five Forces Applied to a Door

preview_player
Показать описание
Shows how to calculate the torque from 5 different forces that are applied to a door. Examples will be shown for forces that are and are not at applied at a right angle to the door.

Torque is a rotating force. It is a measure of how much force is acting on an object that causes the object to rotate. The object will rotate about an axis, which is called the pivot point. It is labeled with the letter P or O. The distance from the pivot point to the point where the force acts is called the moment arm or the lever arm. This distance is labeled with the letter r. This distance r is also a vector, and points from the axis of rotation to the point where the force acts. The force is labeled with the letter F.

I've been watching your videos for about two years now. I hope you become as successful as Sal Khan! I find your videos to have the perfect amount of information with super digestible explanations. Thanks for all your efforts! You've truly impacted my education in a positive way. :)

I’m watching this an hour before my AP physics exam and feeling much more confident on Torque fundamentals! Thank you!

+RE: (T4) +30N x 0.9m x sin (120) = 23N/m OUT. When I multiply 30N by sin(120) i.e. Following your suggestion, my answer is 25.98 N/m NOT 17.4 N/m. What am I doing wrong here !

How do you determine the torque on a rear bicycle wheel?

Great video!
However I believe the vertical component of the 30N force is 27N
Sin120x30N correct?

Very clearly explained and the pacing was great. It made so much sense.

I am a 3rd-year biomechanics major and these have been some of the best explanations of torque I have seen

How can I find torque for this application ?


Specification : Sheet metal to bend in this center, 7 mtrs length and 0.5 to 1.1mm thickness

hii thank for your videos but my doubt is how you find out the force or you assumed?

I recently found your page and really appreciate the clear, concise explanations you provide. My question is about the order in which the equation is arranged. In your previous videos you have the r vector in front of the force vector. Is there any specific reason why they are rearranged in this video? I'm assuming it doesn't matter, but was just curious. Thanks again for all your work!

You talking too fast shows that you are 1/2 educated .. pls don't show more knowledge than you have, remain in bounds of your ability
