Question $6$

A truss analysis includes consideration of Joint $B$ as shown. If $Bx$ is $7\mathrm{.}2$ kips and $By$ is $9\mathrm{.}3$ kips,

find member force $BC$ in kips. Use positive for tension and negative for compression. The

horizontal distance from $A$ to $B$ is $16ft,$ the horizontal distance from $B$ to $C$ is $18$ feet, and the

vertical distance from $A$ to $B$ and $C$ is $12ft.$
