Question $1$: By Force Method determine the reactions at the supports, then draw the shear force and bending moment diagrams. Assum the support at $\backslash ($ A $\backslash )$ is a pin and $\backslash ($ B $\backslash )$ and $\backslash ($ C $\backslash )$ are rollers. The support at C collapses vertically by $10$ mm $.$

Note! The value work method for displacements $\backslash ((\backslash$Delta$)\backslash )$ choosing origin for $\backslash ($ x$\_\{1\}\backslash )$ at $\backslash ($ A $\backslash )$ and $\backslash ($ x$\_\{2\}\backslash )$ at $\backslash ($ C $\backslash ).$ Also take redundant at C$.$
