A bimetallic bar consisting of a copper core se- curely bonded to two steel strips (see figure) is heated uniformly by an amount AT. Assuming that the width of the bar is b, the length is L. and the thickness of each layer is t, determine the stresses , and o, in the steel and copper, respectively. Also, draw free-body diagrams of each of the three strips.

Answer rating: 100% (QA)
To determine the stresses in the steel and copper layers of the bimetallic bar we can start by considering the thermal expansion of each material and the constraint imposed by their bonded interface L... View the full answer
