Give the following problem a try. If you get stuck, here is one way to work it: Essential Solution Video.

A horizontal load $P$ is applied to an assembly consisting of two inclined bars, as shown in the figure. The cross$-$sectional area of bar $(1)$

is $1\mathrm{.}65in.{?}^2,$ and the cross$-$sectional area of bar $(2)$ is $1\mathrm{.}75in.{?}^2.$ The normal stress in either bar may not exceed $20$ksi. Determine the

maximum load $P$ that may be applied to this assembly. Assume dimensions of $a=18\mathrm{.}0ft,b=8\mathrm{.}5ft,$ and $c=11\mathrm{.}0ft.$

Part $1$

Determine the allowable force $F_1$ in member $(1)$ and the allowable force $F_2$ in member $(2).$

$F_{1\text{a}\text{l}\text{l}\text{o}\text{w}}=$ kips

$F_{2\text{a}\text{l}\text{l}\text{o}\text{w}}=$ kips
