A massless, horizontal beam of length L and a massless rope support a sign of mass m (see figure below). (a) What is the tension in the rope? (Use the following as necessary: m, g, d, L, and 6.) (b) In terms of m, g, d, L, and 9, what are the components of the force exerted by the beam on the wall? (Assume that the +xaxis is to the right and the +y-axis is up along the page.)
