This physics video tutorial provides a basic introduction into torque which is also known as moment of force. Torque is the product of force and lever arm also known as moment arm. The lever arm is the perpendicular distance between the axis of rotation and the line of action of the force. Torque is the rotational equivalent of force. Positive torque values produce counterclockwise rotation and negative torques produce clockwise rotation. This video contains plenty of examples and practice problems of torques as it relates to doors, seesaws, and shovels. It discusses how to calculate the mechanical advantage of simple machines like seesaws and shovels.

Could I somehow do the closed captions for this video for you? I'm not huge into making YT videos so I don't know how it works, but this video could really use formal captions. :)

Shouldn't the answer to the problem at 12:54 be 1965.8 Nm? F3= (500cos(50))(5m) because we need the adjacent component to the angle theta. If I'm wrong can someone explain why we can use sin?

4:01 The angle between two vectors is the one when the two vectors are meeting tail to tail and its direction is counterclockwise; in such scenario the angle has to be (180-theta) which in fact is equal to sin theta.
