Problem $2.$

Given the indeterminate beam below, determine the most possible plastic hinge locations subject to the concentrated loads $\backslash ($ Q $\backslash ).$ Then determine the ultimate $\backslash ($ Q$\_\{$p$\}\backslash )$ when the hinges are formed leading to the collapse. Note that the first load is $1\mathrm{.}5$ times of the other one.

$-$ Hint: we had a class example; please first refer to the example before you look at this attached solution hint.

$($without saying, the material behavior follows a bilinear model as shown below$).$
