A helical spring in which the slope of the helix may be assumed small is required to transmit a maximum pull of 1500N and extend 12mm for 250N load. Suppose the mean diameter of the coil is to be 85mm. Find the suitable diameter for the wire and the number of coils required. Take G = 80GPa and allowable shear stress as 110 MPa.
