SOLVED PROBLEM 1.18
A load P is applied to a steel rod supported as shown by an aluminum plate into which a 12-mm-diameter hole has been drilled. Knowing that the shearing stress must not exceed 180 MPa in the steel rod and 70 MPa in the aluminum plate, determine the largest load P that can be applied to the rod.

i don't understand the shear area of aluminum shouldn't we substract the hole part ?? like 40-12 ?? because there no aluminum in there no ?

[@waelsaad588]

like the net area, shouldn't we remove the area of the hole
