A 1.25 in.-square steel punch is to push through an aluminum plate that is supported on a die, thus forming a square opening in the plate. a. If the allowable compressive stress in the plate is 24 ksi, what is the maximum punching force, in pounds, that this die can exert on the plate? b. If the aluminum has an ultimate shear strength of 6500 psi, find the maximum thickness t, in inches, through which a hole may be punched. Write to three decimal places. Punch force Steel punch Aluminum plate, Die Punched piece
