1. The problem statement, all variables and given/known data How much force is required to punch a hole ½ in. in diameter from a 1/8 in. thick steel sheet of shearing strength 4x104 psi. 2. Relevant equations Shearing Modulus = Pressure/Shearing Strain Pressure = F/A Shearing Strain = DistanceSheared/Length-to-be-sheared 3. The attempt at a solution Can I first ask how can I use the Value of its Shearing Strength to the equation?
