... Two forces act on a wheel, as shown below. The wheel is free to rotate without friction, has a radius of 0.42 m, and is initially at rest. Given that F1 = 12 N and F2 = 9.5 N, find (a) the torque caused by F1 and (b) the torque caused by F2. (c) In which direction does the wheel turn as a result of ...
