Applying force method determine the reactions at support A and spring at B for the beam shown in Figure $2$ below. Cross$-$section of the beam is $5$ mm $($Width$)\backslash (\backslash$times $10\backslash$mathrm$\{$~mm$\}\backslash )($Depth$).$ Assume the support at $\backslash ($ A $\backslash )$ is fixed. $\backslash ($ E l $\backslash )$ is constant.
