You are asked to design a solid circular shaft of minimum cost that is 1.3 m long and has to twist less than 3 degrees for a torque of 15 kN-m. The currently used material is brass, but you have decided to make it from a wrought magnesium alloy. What would be the ratio of costs for the two rods? What would be the ratio of weights?
