Draw the influence lines for $($a$)$ the vertical reaction at A$,($b$)$ the vertical reaction at B$,($c$)$ the shear just to the right of the support at A$,$ and $($d$)$ the moment at C$.$ Assume the support at A is a pin and B is a roller. Solve this problem using the M$$ller$-$Breslau principle. Only solve with Muller Breslau Equation.
