Your stepfather is almost exactly like a $1920$ s oil tycoon, mainly that he is an

oil tycoon, dresses like a fancy man from the roaring twenties, and has a weird

transatlantic accent. You are trying to impress him so you decide to run some

calculations on a stress element right above the bit on his new oil well drill pipe.

The pipe, as shown in the figure, has an outer diameter of $6\mathrm{.}2$ in and a thickness

of $0\mathrm{.}75in.$ and has a torque of $185$kip$-$in being applied to it from drilling. If the

compressive force in the pipe because of its weight is $62$kips please determine

the maximum tensile, compressive, and shear stresses in the drill pipe.
