A conical spiral spring is submitted to the action of an axial force W. Determine the safe magnitude of W if the allowable stress in shear is 120 MPa, diameter of the wire cross-section = 3 cm, radius of the cone at the top of the spring = 5 cm and at the bottom = 20 cm. Determine also the extension of the spring if the number of coils is 8 and G= 80 GPa.
