Rework Problem 12.23 with D = 25 mm and d = 5 mm, and a pitch distance of 7 mm. ASTM B197 beryllium copper spring wire with S= 262.5 MPa

is used for a helical coil spring. The spring is wound with D = 50= 750 MPa and T, < (0.35)- ("s)mm, d = 10.0 mm, and a pitch (distance between corresponding points of adjacent coils) of 14 mm. If the spring is compressed solid, would the spring return to its original free length when the force is removed?
