required to determine the position and nature of theequilibrium. Pressure on Curved Surfaees. 4 Lot AB — ia, BC = 20, s = area of normal section oleach rod, 6 = inclination of AB and 0 = inclination of BCto the vertical. Let G, G be the centres of j^-ravity of therods, and II, IV their centres of… … Fig. 45- equilil)rium of the rod BC, we see that the reaction of ABon BC is a vertical upward force at B equal to W — L\and since the moments of W and L about B are equal andopposite, we have at once = ikh, suppose.
