Question: 

A uniform rod AB of length 5.0 m and mass M = 3.8 kg is hinged at A and held in equilibrium by a light cord, as shown in Fig. 9–67. A load W = 22 N hangs from the rod at a distance $d$ so that the tension in the cord is 85 N.

  1. Draw a free-body diagram for the rod.
  2. Determine the vertical and horizontal forces on the rod exerted by the hinge.
  3. Determine $d$ from the appropriate torque equation.
