help A horizontal beam as in Figure Q$1,$ which is simply supported at its end, A and B$,$ have a uniform cross$-$section and is $14$ m long. Concentrated load of $12$ kN and $8$ kN act at $3$ m from $\backslash ($ A $\backslash )$ and $4\mathrm{.}5$ m from $\backslash ($ B $\backslash )$ respectively. By using Macaulay Method, calculate deflection of the beam at points under the two loads. El$=$ constant.
