Three metal rods are firmly attached to the walls and the middle rigid plate. Rod AB is made from stainless steel and rods CD and EF are made from 2014-T6 aluminum. If a balanced load is applied to the rigid plate, determine what the stresses are in the rods. Follow the sign convention that tensile stress is positive and compressive stress is negative. The parameter values are listed in the table above the figure.
