Extracted text: A load P is applied to a steel rod with head dimensions D = 49 mm, and h = 8.7 mm supported by an aluminum plate of thickness t = 8.7 mm into which a d = 8.2-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, what is the largest load P that can be applied to the rod? P
