(a) A man applies a force of F = 3.00 102 N at an angle of 60.0° to a door, x = 1.90 m from the hinges. Find the torque on the door, choosing the position of the hinges as the axis of rotation.
N · m
(b) Suppose a wedge is placed 1.50 m from the hinges on the other side of the door. What minimum force must the wedge exert so that the force applied in part (a) won't open the door?
N
