CIVIL FNGINEERING Stractural Analysis Question: $1\mathrm{.}22$

Using MOMENT DISTRIBUTION METHOD OF ANALYSIS please assirt with the solution for below question and show all calculations in full exing SI Units:

$($a$)$ Beam A$-$B$-$C$-$D is fixed at A and simply supported at $B$ and $C.$ Draw the bending moment and shear force diagrams.

$($b$)$ If $C$ sinks by $5$ mm $,$ what are the new values of the bending moments?

$E=207$GPa

$I=810{10}^{6}m{m}^4$
