An open-coiled helical spring consists of 12 coils, each of mean diameter 60 mm, wire diameter 6 mm and helix angle 25°. An axial load of 120 N is applied to the spring. Calculate (a) axial de- flection, (b) bending and shearing stresses, and (c) axial torque which shall produce a bending stress of 50 MPa in the coils. Take E 200 MPa, and G = 84 GPa.
