73. (a) Choosing an axis through the hinge, perpendicular to the plane of the figure and taking torques that would cause counterclockwise rotation as positive, we require the net torque to vanish: sin90sin 650FLTh°−°=where the length of the beam is L= 3.2 m and the height at which the cable attaches is h= 2.0 m. Note that the weight of the beam does not enter this equation since its line of action is directed towards the hinge. With
