Problem #$2$: Using the slope$-$deflection method, draw the moment diagram of the following beam. Assume EI is constant. The supports at A and C are fixed; the support at B is a roller Problem $\backslash$#$2$: Using the slope$-$deflection method, draw the moment diagram of the following beam. Assume $\backslash ($ E I $\backslash )$ is constant. The supports at $\backslash ($ A $\backslash )$ and $\backslash ($ C $\backslash )$ are fixed; the support at $\backslash ($ B $\backslash )$ is a roller.
