e. (13) Determine the maximum force P that can be applied to the handle so that control rod AB doesn't buckle. The rod AB has a rectangular cross-section with **1 x 1.5 in.** and of steel alloy (E = **30 Msi**) It is pin-pin connection at two ends. If this max force P applied, what is the shrinkage $$\delta$$ of rod AB?
