Using the principle of transmissibility, the force F can be slid along its line

Question

Using the principle of transmissibility, the force F can be slid along its line of action to point B. At point B, the force F creates an angle with the shed. (Figure 3) What is MFx, the contribution to the moment about point O made by the x component of the force F at point B? What is MFy , the contribution to the moment about point O made by the y component of the force F at point B? What is the total moment M due to the force F about point O? Assume that moments acting counterclockwise about point O are positive whereas moments acting clockwise are negative.

Explanation / Answer

Fx = Fsin(phi) Fy = Fcos(phi) MFx = Fx X l = Flsin(phi) MFy = 0 since distance and force are in same direction Total moment = Flsin(phi)
