In the triangular truss shown above, the forces in each strut act at the ends only and are parallel to the strut. External forces W and G act vertically at nodes 2 and 4, and external force H acts horizontally at node 5. The truss is supported by the horizontal force Fg and vertical force Fg at node 1 and by the vertical force F10 at node 3. The angles are a=47, B=66, y=45, 8=79, and W=350, G=390, H=240. The equations for the unknown forces F1 - F10 are: = 0 = 0 = 0 Fix + F6 + Fe Fly + F9 -F2x + F3x F6 + F7 F2y + F3y = W -F4x F7 = 0 Fay + F10 = 0 -F1x + F2x + Fs = 0 -Fly F2y = G -F3x + F4x Fs = H -F3y F4y = 0 G4 Fs F3x H 5 Fex F2x Fs Fay..
