Homework Statement
In tightening a bolt whose center is at point O, a person exerts a 56-lb force on the ratchet handle with his right hand. In addition, with his left hand he exerts a 10-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.

Homework Equations
The Attempt at a Solution
I calculated the resultant and moment as follows:
Rx = 0
Ry = -10 lb
Rz = -56 lb
Mx = (-56lb)(2.1 inches) = -117.6 ln-in
My = (-56 lb)(6.5 inches) = -364 lb in
Mz = 0
I fairly certain that the above values are correct. My confusion is with calculating the point on the x-y plane through which the line of action passes. I would appreciate any help. Thanks
