1) Fixed end moments (FEM) :

AB =>
$M_{ab}$ =$\frac {-wl^2}{12}$ = $\frac{-10*3^2}{12}$ = -7.5 KN.m

$M_{ba}$ = $\frac{wl^2}{12}$ = $\frac{10*3^2}{12}$ = 7.5 KN.m

BC =>

$M_{bc}$ = $\frac{-wl}{8}$ = $\frac{-8*4}{8}$ = -4 KN.m

$M_{cb}$ = $\frac{wl}{8}$ = $\frac{8*4}{8}$ = 4 KN.m

2) Stiffness (K) :

$K_{ba}$ = $\frac{HEI}{l}$ = …
