For the tapered solid circular shaft shown in Figure P9–24,
a semicircular groove has been machined into the side. The shaft is made of a
hot rolled 1040 steel alloy with yield strength of 71,000 psi. The shaft is
subjected to a uniform axial pressure of 4000 psi. Determine the maximum
principal stresses and von Mises stresses at the fillet and at the semicircular
groove. Is the shaft safe from failure based on the maximum distortion energy theory?
