Question
In tightening a bolt whose center is at point O, a person exerts a 54-lb force on the ratchet handle with his right hand. In addition,
with his left hand he exerts a 30-lb force as shown in order to secure the socket onto the bolt head. Determine the equivalent force-
couple system at O. Then find the point in the x-y plane through which the line of action of the wrench passes.
