Problem $04\mathrm{.}112-$ Calculate the reactions of a statically indeterminate bar

A rectangular aluminum bar $10\mathrm{.}40$ mm thick and $60$ mm wide is welded to fixed supports at the ends, and the bar supports a load $W=4\mathrm{.}100kN,$ acting through a pin as shown. Find the reactions at the supports and the deflection of point $A.($Round the final answers to three decimal places.$)$

The reaction force at B is The reaction force at $O$ is The deflection at point A is
