Problem
A light horizontal rod 0.80 m long is hinged at its left end. A 12 N force is applied at the right end at 30° above the rod, and a 9.0 N force is applied straight downward at a point 0.50 m from the hinge. Taking counter-clockwise torques as positive, calculate the net torque about the hinge.
