Determine the average punching shear stress the circular shaft creates in the metal plate through section AC and BD. Also, what is the maximum bearing stress developed on the surface of the plate?

Average punching share stress:

T _avg = V/A;

V = 75 x 10 ³ /2

V = 37,500 N

A C 75 kN 65 mm -70 mm- 100 mm B D [10 mm
