Argh!!! Statics is a pain. Argh, this problem is killing me. I've tried a couple of approaches to this proble. First approach was to break it into 4 'Y' shaped vectors with with points A,B,C,D as the centers of the 'Y'. No avail. The next approach was to couple the forces to the origin but the forces cancel out when I do that. The third approach was to divide the quadralateral into 4 triangles with the y-axis equal to 1/2 y = 30lbf, and x-axis = (2-s)=1/2(s)(40). Again to no avail. Any help would be appreciated. Thanks a lot.
