Two forces, F1 and F2, have the same magnitude and both act on an object that can rotate about a fixed axis of rotation. If the forces F1 and F2 point in opposite directions, and the torque produced by F1 is clockwise, then the torque produced by F2 must be counterclockwise.

True or false?

Answer #1

The statement is false.

Torque is given by: x , where is position vector and is fore vector.

So, direction of torque depends on both position and force vectors. Direction of torque cannot be decided only by the direction of force.

In the given scenario, only information about direction of force is given. So, we cannot comment on the direction of torque.

Two forces F1 and F2 act on an object. Each force is specified as an ordered pair: its magnitude in Newtons and an angle measured in degrees counter-clockwise from the positive x-axis. Let F1 = (27.0 N, ∠115° )and F2 = (83.0 N, ∠240° ). Calculate the magnitude the vector F1 - F2. Include three significant figures in your answer. (If the last digit is a zero, Canvas will not display it but that's OK.) Please HELP!
