A vertical compound tie member fixed rigidly at its upper end, consists of a steel rod 3 m long and 20 mm diameter, placed within an equally long brass tube 20 mm internal diameter and 20 mm external diameter. The rod and the tube are fixed together at the ends. The compound member is then suddenly loaded in tension by weight of 1200 kgf falling through a height of 5 mm on to a flange to its lower end. Calculate the maximum stresses in steel and brass. Assume Es = 2X10⁶ kgf/cm² and brass Eb = 1.0X10⁶ kgf/cm² .
