Consier a long (length= 15m) uniform wooden beam (mass= 60 kg)attached horizontally to a wall that can only support a vertical load (The horizontal component of the force of the wall on the beamis identically zero.). There is a chandelier (mass= 40kg)hanging at a distance= 4.21 meter from the end of the beam that isattached to the wall. There is a vertical cable hanging downfrom the ceiling that is attached to the other end of the beam thatis in mid air. The entire structure is in staticequilibrium. Determine the tension in the vertical cable.

Suppose that in Sherwood Forest, the average radius of a tree is R= 1 m and the average number of trees per unit area is 0.005m^(−2). If Robin Hood shoots an arrow in a randomdirection, how far, on average, will it travel before itstrikes a tree?
A crate is pulled by a force (parallel to the incline) up a rough incline. The crate has an initial speed of 1.5m/s. The crate is pulled a distance of 7.5 m on the incline by a 150 N force. The acceleration of gravity is 9.8m/s² mu=0.15
