What is the stress in the steel with E = 29,000 ksi?arrow_forwardTension and compression occur in a partially supported horizontal beam when it sags due to gravity or when it supports a load. Make a simple sketch to show a means of supporting the beam so that tension occurs at the top part and compression at the bottom. Sketch another case in which compression is at the top and tension occurs at the bottom.arrow_forwardThe support consists of a solid red brass C83400 copper post surrounded by a 304 stainless steel tube. Before the load is applied the gap between these two parts is 1 mm.
