A solid part shown in Figure P11-28 is made to locate parts into proper position. The material is AISI 1005 steel with E = 200 GPa and v = 0.29. The front faces are fixed, and a pressure P of 100 MPa is applied to the semi-circular face of the inside slot, as shown in the figure. Determine the largest von Mises stress and its location on the locator device.
