The solid rod shown in the figure is of diameter d 15 mm and passes through a hole of diameter D 20 mm in the support plate. When a load P is applied to the rod, the rod head rests on the plate, which has a thickness b 12 mm. The rod head has a diameter a 30 mm and a thickness t 10 mm. If the normal stress produced in the rod by load P is 225 MPa, determine (a) the average bearing stress MPa acting between the support plate and the rod head. (b) the average shear stress MPa produced in the rod head. (c) the punching shear stress MPa produced in the support plate by the rod head.

The solid rod shown in the figure is of diameter d 15 mm and passes through a hole of diameter D 20 mm in the support
plate. When a load P is applied to the rod, the rod head rests on the plate, which has a thickness b 12 mm. The rod head has
a diameter a 30 mm and a thickness t 10 mm. If the normal stress produced in the rod by load P is 225 MPa, determine
(a) the average bearing stress MPa acting between the support plate and the rod head.
(b) the average shear stress MPa produced in the rod head.
(c) the punching shear stress MPa produced in the support plate by the rod head.
