As the Figure shows, a rigid beam, AB, hanged via 3 vertical bars with the same lengths and cross sectional areas (0.1 in2). The middle bar is made from steel while the others are from copper. The temperature of bars increases 10 oF and [...]

Consider the planar truss with shape of power tower shown in the Figure. The points S and T are attached to the ground to constrain them in all directions. All cross members like CD and BE are made of [...]
Consider the truss shown in the Figure including 9 members, which can rotate freely at the joints. The whole system is constrained at two points of A and D and a roller support of B. The members CE and [...]
