A hard-drawn steel wire extension spring has a spring index Of 7.5, hook radii of r 0.106 in and r2 0.089 in, and an initial tension of 1.5 lbf. The number of body turns is 13.5 and the uncorrected initial stress is 16.5 kpsi. From the given information: (a) Determine the physical parameters of the spring. (b) Find all stresses at ends A and B and the body torsion under the static load of 6 Ibf.
