In Fig, 12-52, uniform beams A and B are attached to a wall with hinges and loosely bolted together (there is no torque of one on the other). Beam A has length LA = 2.40 m and mass 54.0 kg; beam B has mass 68.0 kg. The two hinge points are separated by distance d = 1.80 m, In unit-vector notation, what is the force on (a) beam A due to its hinge, (b) beam A due to the bolt, (c) beam B due to its hinge, and (d) beam B due to the bolt?
