Chapter 11.3, Problem 12P
A single 6-mm-diameter steel pin B is used to connect the steel strip DE to two aluminum strips, each of 20-mm width and 5-mm thickness. The modulus of elasticity is 200 GPa for the steel and 70 GPa for the aluminum. Knowing that for the pin at B the allowable shearing stress is τall = 85 MPa, determine, for the loading shown, the maximum strain energy that can be acquired by the assembled strips.

The rigid bar ABD is connected to the rod BD which consists of a single bar with a width of 25,0 mm and a thickness of 13 mm. Knowing that each pin has a diameter of 10 mm determine the value of the maximum average normal stress on rod BD considering the angle θ=90°.
