Consider a rigid steel beam of length L = 13 m and mass mb = 378 kg resting on two supports, one at each end. A worker of mass mw = 61 kg sits on the beam at a distance x from support A. Refer to the figure, though note that it is not drawn to scale. Enter an expression for the force support B must exert on the beam in order for it to remain at rest, in terms of defined quantities, x, and g. FB = When the worker sits at a distance x = 8.5 m from support A, calculate the force, in newtons, that support B must exert on the beam in order for it to remain at rest. Use g with three significant figures. FB = The force exerted on the beam by support A is measured and found to be FA = 2280 N. At what distance x, in meters, from support A is the worker sitting now?

A fence post of mass m = 8 kg supports a fence with three lengths of barbed wire. The bottom wire is a distance d = 0.35 m from the ground and each wire is a distance 0.35 m above the previous one. Each of these three wires has the tension on it. For this problem, assume that the force exerted by these wires is purely horizontal. An additional guy wire is used to keep the pole upright with a tension of Fa = 490 N. The guy wire attaches to the post at a point h = 0.86 m above the ground and makes an angle of θ = 45 with respect to the horizontal. Write an expression for the tension in any one of the three fence wires. What is the normal force that the ground exerts upward on the post?
