The figure illustrates a stepped torsion-bar spring OA with an actuating cantilever AB. Both parts are of carbon steel (Young's modulus is 207 GPa and shear modulus is 79.3 GPa). Use Castigliano's theorem to find the spring rate k corresponding to a force F acting at B. Hint: you need to consider the bending of member AB and torsion of member AO. 12 mm OC 18 mm 8 mm 0.2 m 0.4 m
