For the following problem, assume the modulus of elasticity for steel to be 30,000,000 psi (207 000) and the proportional limit to be 34,000 psi (234 MPa). Refer to Appendices F or G for other materials.

Compute the force required to punch a 1-in.-diameter hole through a .-thick boiler plate. The ultimate shear strength for the material is 42,000 psi.
