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

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

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

Thus,

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

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

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