Q$3[30\%][$Ch$.9]$

Beam Deflection $-$ A simply supported beam with the cross$-$section shown in Fig. spans $24$ ft and supports a dead load of $1\mathrm{.}5$kip$\frac{s}{f}t,$ including its own self$-$weight plus a live load of $1\mathrm{.}2$kip$\frac{s}{f}t.$ The concrete strength is $5000$ psi. Compute

the immediate dead$-$load deflection;

the immediate dead$-$plus$-$live$-$load deflection
