A machine component is undergoing a torque load. The part is made up of a 1 m long composite bar. It comprises an inner solid bar of radius 10 mm which is perfectly bonded inside a tube of outer radius 20 mm. If given that the shear moduli of the inner solid bar and outer tube are 48 GPa and 25 GPa respectively, and the composite bar is subjected to a torque of 10 kNm, a) Determine the angle of twist of the composite bar b) Determine the maximum shear stresses in both the inner solid and outer tube
