1. The figure illustrates a stepped torsion-bar spring
OA
with an actuating cantilever
AB. Both parts are of carbon steel. Use superposition and find the spring rate
k
corresponding to a force
F
acting at
B.

2. Consider the simply supported beam 5 with a center load in Appendix A–9. Determine the deflection equation if the stiffness of the left and right supports are
k1 and
k2 , respectively.

3.Consider the simply supported beam 10 with an overhanging load in Appendix A–9. Determine the deflection equation if the stiffness of the left and right supports are
k1 and
k2 , respectively.
