Photo of a rust-red steel hand-operated winch or lifting post: a vertical square post on a flat base plate, with a swivel arm and a hook at the top, held by a pin with a spring clip.


So i am confused on how to do the analysis on the pin where the hook attaches to the arm.

would their be a shear and a torque at that point?
 

Discussion

Based on this photo, it appears that the hook is allowed to rotate, with the pin serving as an axis. IMO, torque = 0.
