QUESTION $1$

A compact car weighing $2300$ lb is lifted by a crane as shown below. The car is fastened to a steel cable of cross$-$sectional area $A=0\mathrm{.}25i{n}^2,$ which is attached to a steel hook. The upper part of the hook is a prismatic rod of uniform crosssectional area $A^{\text{'}}=0\mathrm{.}40i{n}^2.$ Neglecting the weights of the hook and the cable, calculate the normal stresses in the cable and the rod.
