cross$-$sectional area. The slope angle $$ can also be determined using the method of virtual work. Instead of a unit load, a unit couple moment is applied at the desired point. Once corresponding internal real moments $M$ and virtual moments $m_0$ have been determined, as a function of $x,$ then the virtual work equation $1*={\displaystyle \underset{0}{\overset{L}{}}}\frac{m_{}M}{EI}dx$ can be used to find the

Part C

For the frame shown in $($Figure $3),$ determine the horizontal deflection at $C$ when $a=6ft,b=18ft,$ and $w=120\frac{k}{f}t.$ Assume $A$ is pinned, $C$ is a roller, and $B$ is fixed. Take $E=2\mathrm{.}9{10}^4$ ksi and $I=800$ in ${?}^4.$

Express your answer in the appropriate units to three significant figures.
