FEM's (Fixed End Moments)

$AB = M_{ab} = \frac{-wl^2}{12} = \frac{-40*3^2}{12} = -30KN.m$

$AB = M_{ba} = \frac{wl^2}{12} = \frac{40*3^2}{12} = 30.m$

$BC = M_{bc} = \frac{-wl}{8}=\frac{-100*2}{8} = -25KN.m$

$BC = M_{cb} = \frac{wl}{8}=\frac{100*2}{8} = 25KN.m$

$CD = M_{cd} = \frac{-wl^2}{12} = \frac{-50*3^2}{12} = -37.5KN.m$

$AB = M_{dc} = \frac{wl^2}{12} …
