saw that the action of the bar QP on the pin Pis represented by hd, hence dh is the action of the pin onthe bar, that is the bar is subjected to a compression, such abar is called a strut. The action of the bar QR on Q isrepresented by cd, and therefore dc represents the actionof the pin on the… … Fig. 147. The supporting forces BG and GA at P and S are onlygiven in direction, not in magnitude, we shall now find theirmagnitudes. Draw ab to represent W on some scale, theforces BC and CA are represented by he and ca but theposition of c is not as yet known. Take any pole 0 andjoin Oa and Ob,…
