Question

The assembly consists of two red brass C83400 copper rods AB and CD with a diameter of 30 mm; a stainless 304 steel alloy rod EF with a diameter of 40 mm; and a rigid cap. The supports at A, C, and F are rigid. Part A: The modulus of elasticity for copper is Ecopper = 101 GPa. The modulus of elasticity for steel is Estcel = 193 GPa. Determine the average normal stress developed in the rod AB. Express your answer to three significant figures and include the appropriate units. Part B: Determine the average normal stress developed in the rod CD. Express your answer to three significant figures and include the appropriate units.
