Solve Example 5.14 including the effects of shear force and normal force in the wire. Plot the relationship between spring stiffness and pitch angle β to demonstrate the relative contributions of torsion, bending, shear, and normal force for a spring with a single coil (nc = 1), coil diameter D = 100 mm, wire diameter d = 10 mm, modulus of elasticity E = 200 GPa, and Poisson’s ratio ν = 0.3. Consider 0 ≤ β ≤ 30°.
