Determine the maximum allowable torque T that can be transmitted by the joint. The shear pin A has a diameter of d=27mm, and it is made from one of materials listed in the table below (make your own choice). The width of the fork is L=100mm. Apply a safety factor of 3.0 against failure. Note: (Optional) You can try to solve this problem using two different yield criteria learned in the class. The choice of the yield criterion will affect your result for the allowable torque T. The more conservative yield criterion provides a smaller allowable torque
