A 12"x36" and 9" high empty prism composed of a material with an Elastic modulus of 345,000 psi, 9,000 psi yield stress, the walls of the prism are 0.74" thick, and weight of 40 pounds is placed on a pedestal in which the surface that makes contact with the prism is 2"x2" , the box's surface is the 12"x36" side, and the 2"x2" surface is directly in the center of the prism. What is the stress caused on the prism by being placed on this pedestal, what are the moments if any exist.
