A load P is supported by two springs arranged in series. The upper spring has 20 turns of 19 mm diameter wire on a mean diameter of 150 mm. The lower spring consists of 15 turns of 12 mm diameter wire on a mead diameter of 125 mm. Determine the spring index of the lower spring in MPa if the total deformation is 76 mm and G of 83 GPa.
