For the given beam with $\backslash ($ E I$=\backslash )$ constant, do the following:

a$.$ First, obtain the reactions at A and B $(4$ points$)$

b$.$ Draw the bending moment diagram and then the $\backslash (\backslash$frac$\{$M$\}\{$E I$\}\backslash )$ diagram. $($if this is wrong, the following steps will be wrong so be careful$)(4$ points$)$

c$.$ Use the second$-$moment area theorem expression considering the points A and B to obtain $\backslash (\backslash$theta$\_\{$A$\}\backslash )($hint: we already know that the vertical displacement of the points A and B are $0)(4$ points$)$

d$.$ Now use the first$-$moment area theorem expression between the points A and C to find $\backslash (\backslash$theta$\_\{$C$\}\backslash )($hint: we have already found $\backslash (\backslash$theta$\_\{$A$\}\backslash )$ in the previous part$)(4$ points$)$

e$.$ Now use the second moment of area theorem between the points A and C to find the deflection at point $\backslash ($ C $\backslash )($hint: we have already found $\backslash (\backslash$theta$\_\{$A$\}\backslash )$ in the previous parts$).(4$ points$)$
