Halliday, Resnick & Walker — Equilibrium and Elasticity: Problem 27

27 A 1500 kg load is hung from the free end of a horizontal aluminum rod of length 7.0 cm, diameter 9.6 cm, and negligible mass. The other end of the rod is fixed in place. The shear modulus of aluminum is \(3.0 \times 10^{10} \text{ N/m}^2\). Find (a) the shear stress on the rod and (b) the vertical deflection of the rod’s free end.
