Problem $2$

The member shown in Fig. has a rectangular cross section. Determine:

i$-\backslash (\backslash$quad $\backslash )$ The internal reactions at the section passing by points $\backslash ($ C $\backslash$& D $\backslash )$ that are at a distance of $1\mathrm{.}5$ m away from end A $.$

ii$-$ Hence determine the state of stress that the loading produces at point $\backslash ($ C $\backslash )$ and point $\backslash ($ D $\backslash ).$
