The wrench blanks, and the final wrench produced with the CNC machine, will be made from 6061-T6 aluminum alloy. With a factor of safety of 2, determine (i) the maximum force that can be applied to the handle, and (ii) the maximum torque produced by the wrench in tightening a bolt, both before yielding will occur. Draw a FBD of the wrench when you do the calculations.
