A punch for making holes in steel plates is shown in Fig. a. below. Assume that a punch having diameter d = 20 mm is used to punch a hole in an 8 mm plate, as shown in the cross-sectional view (Fig. b). If a force P = 110 kN is required to create the hole, what is the average shear stress in the plate and the average compressive stress in the punch?
