 Determine the force required to punch a 2" square blank from.250"

Determine the force required to punch a 2" square blank from.250" thick aluminum 6061-T6 plate when the shear strength of the aluminum is 40,000 psi. Assume that the end of the punch and top of the die lie in substantially parallel planes (show calculation). Can we use a 40-ton press to perform this operation? Using the same material determine the clearance required for a 3% allowance, Given formulas: F = SLT F = STDT c = at
