Q$.3$ Figure $7$ shows a continuous beam with cantilever at the end. Determine the moments at $\backslash (\backslash$mathrm$\{$A$\},\backslash$mathrm$\{$B$\}\backslash )$ and C by moment distribution and draw the shear force and bending moment diagram for the beam. Assume the support at $\backslash ($ A $\backslash )$ is fixed and $\backslash ($ D $\backslash )$ is free end. $\backslash ($ B $\backslash )$ and $\backslash ($ C $\backslash )$ are rollers. El is constant.
