ASTM B197 beryllium copper spring wire with S_u = 750 MPa and τ_s ≤ (0.35) (S_u) = 262.5 MPa is used for a helical coil spring. The spring is wound with D = 50 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?
