Problem 5-4 An open-coiled helical spring of 5 cm mean dia- meter is made of steel of 6 mm diameter. Calculate the number of turns required in the spring to give a deflection of 12 mm for an axial load of 250 N if the angle of helix is 30°. Calculate also the rotation of one end of the spring relative to the other if it is subjected to an axial couple of 12-5 N.m. E = 210 GPa and G = 84 GPa. %3D
