A gradually applied load W is suspended by with ropes AB and CD as shown in the figure. The wires AB and CD, made of the same material and of the same cross-section are connected to a rigid block from which the load W is suspended in such a way that both the ropes stretch by the same amount. If the stress in AB and CD are p1 and p2 respectively, then the ratio - will be -A-B-C-D--A-
