When the forces Fx and Fy act on the point C of the structure as shown in the figure, the force FAC on the member AC is obtained as follows.

Assuming that the horizontal reaction force at point A is in the + x direction and as  the moment at point B is 0, the following equation can be made. (Clockwise: +)

Fx*(H1+H2)+Fy*L+FAC*H2*L/(L^2+H1^2)^(1/2) = 0

Thus,

FAC = -(Fx*(H1+H2)+Fy*L)*(L^2+H1^2)^(1/2) / (H2*L)

If FAC is +, the member receives a compressive force. If FAC is -, it is subjected to a tensile force.

*** 참고문헌[References] ***
FAC = -(Fx*(H1+H2)+Fy*L)*(L^2+H1^2)^(1/2) / (H2*L)
