A helical spring in which the mean diameter of the coil is 8 times the wire diameter is to be designed to absorb 0.2 kNm of energy with an extension of 100 mm. The maximum shear stress is not to exceed 125 N/mm2 . Determine the mean diameter of the spring, diameter of the wire and the number of turns. Also find the load with which an extension of 40mm could be produced in the spring. Assume G = 84 kN/mm2
