Question
An overhead view of a door is shown. If the compressive force F acting in the coupler arm of the hydraulic door closer is 20 lb with the orientation shown, determine the moment made by this force about the hinge axis O. The moment is positive if counterclockwise and negative if clockwise.

Moment
M0 = 20cos20 x 16 + 20sin20 ( 1.125+1.375+1.25)
M0 = 326.353 lb-in
