For the beam and loading shown, P$=66$ kip, L$=13$ ft$,$ E$=29$x$106$ psi. Determine the slope and deflection at C$.$

Superposition principle

If we superpose the solution for the statically derminate beam into $($I$)+($II$)$Using units of $($kip$,$ ft$)$P$=66$ kip, L$=13$ ft$,$E$=29\backslash$times $103($kipin$2),$ I$=228($in$4)($from App. E$)$EI$=45\mathrm{.}917\backslash$times $103($kip$$ft$2)$

For $($II$),$

$($a$)$ the deflection at C is given as

$($in$)()$

$($b$)$ the slope $($~angle$)$ at C is

$($degree$)$
