Question

A hard-drawn steel wire extension spring has a wire diameter of 4mm, an outside coil diameter of 28 mm, and initial tension of 1200 N is applied to the spring. The spring shows an extension of 85 mm. The approximate number of turns is 25. From the given information:

  1. Determine the physical parameters of the spring such as mean diameter, spring index, maximum shear stress, total number of turns, Wahl’s stress factor, free length of the spring, and pitch of the coil
