Required information

The rigid bar $AD$ is supported by two steel wires of $\frac{1}{16}-$in$.$ diameter $(E=29{10}^6)$ and a pin and bracket at $D.$ The

wires were initially taut when a $120-$lb load $P$ was applied at $B.$

Determine the additional tension in each wire when the load $P$ is applied.

The additional tension in wire $AE$ is

lb$.$

The additional tension in wire $CF$ is

lb$.$
