Question

A bar BD is held in a horizontal position when there is no
load by the steel wire AB. When a weight Wis added at C,
also hanging from a steel wire CE, then point C is displace
down by 0.025in. The cross-sectional area of the wires is
0.002in². The wires are made of a steel alloy with
E = 29000ksi and oy = 70ksi. Calculate the strain in both
wires, and the weight W.
