For the tapered solid circular shaft shown in Figure P9–24, a semicircular groove has been machined.
For the tapered hard spherical stem shown in Figure P9–24, a semispherical corrugation has been machined into the plane. The stem is made of a hot rolled 1040 steel deterioration after a while surrender force of 71,000 psi. The stem is subjected to a even axial exigency of 4000 psi. Determine the completion principal stresses and von Mises stresses at the fillet and at the semicircular groove. Is the stem certain from scarcity based on the completion undelineation motive scheme?
