since each striphas its centre on Bx, each willbalance separately, and, therefore,the whole will balance. Now, in figure 125, take the middle point of AB and join CZ. The triangle will also balance uponCZ for the same reason as before. The centre of gravity being,therefore, in Bx, and also in… … Fig. 125. ENGINEERING ESSAYS. 343 For this reason, triangle ABx = triangle CBat also \Ox = COx, subtracting the latter from the former triangle ABO = CBO but ABO = twice ZBO .-. CBO = twice ZBO ; Now thelse two, triangles have each the same vertex B, therefore,the base CO must be twice thef base…
