Question: A fork from a forklift is constrained by two bars (not shown) that fit into each L-shaped appendage on the vertical part of the fork

A fork from a forklift is constrained by two bars (not shown) that fit into each L-shaped appendage on the vertical part of the fork as shown in Figure P11-21. The fork is made of AISI 4130 steel with E = 206.84 GPa, v = 0.30, and a yield strength of 360 MPa . The fork is loaded with 46,189 N/m2 of surface traction on the top surface. How much will the fork deflect, and what is the maximum von Mises stress? What is the factor of safety against yielding of the material? (This problem is by Jay Emmerich.)
