Homework Statement




How much force is required to punch a hole 1/2 inch in diameter from a 1/8 inch thick sheet of steel with a shearing strength of 4x10^4 PSI?



Homework Equations




Formula goes like this

Shearing Modulus = (Force/Area) / (Shearing Length/Length to be sheared)

The Attempt at a Solution



Force = ?
Area = ∏(d^2/4)
Shearing Length = ?
Length to be sheared = 1/8 inch

My problem now is i cannot find out how to get the shearing length that is needed to solve the equation.

Solving the equation regardless of the shearing length value will yield:

= 63 kPSI * Shearing Length
