A worker of weight 758.6 kg stands on the end of a beam of weight 1651 N and length L= 109.2 m, supported on a pivot. The beam's center of mass is at its center. W is the weight of a counterweight needed to hold the beam in equilibrium. Determine the counterweight W (in N) if the distance between the counterweight and the fulcrum is x= 29.2 m.

Ruby, with mass 55.0 kg, is trying to reach a box on a high shelf by standing on her tiptoes. In this position, half her weight is supported by the normal force exerted by the floor on the toes of each foot as shown in Figure P14.75A.

A rod of length 4.00 m with negligible mass is hinged to a wall. A rope attached to the end of the rod runs up to the wall at an angle of exactly 45, helping support the rod, while a sign of weight 10.0 N is hanging by two ropes attached to the bottom of the rod.
