Given that the shear bolt is made of steel with a tensile yield strength of 36 ksi and tensile ultimate strength of 60 ksi, the bolt center is 2" away from the axis of the PTO shaft, and the table of UNC thread specs on the next page, Find the type of bolt (e.g., \"-20) that would transmit closest to 700 ft-lb of torque. • You may make simplifying assumptions as long as you explain them. • For one thing, assume that all torque is carried by the bolt. That is, assume that the nut and bolt are tight enough to remain in place, but not tight enough to create significant friction between the plates.
