One arm of a crimper tool shown in Figure P7-37 is to be designed of 1080 as-rolled steel. The loads are shown in the figure. Fix the nodes around the two holes. Select a thickness for the arm based on the material not yielding with a factor of safety of 1.5. Recommend any other changes in the design. (Scale any other dimensions that you need.) Remember stresses at concentrated loads are false.
