A clockwise couple $\backslash (\backslash$boldsymbol$\{$M$\}\backslash )$ is resisted by the shaft of the electric motor. Determine the magnitude of the reaction forces $\backslash (-\backslash$mathbf$\{$R$\}\backslash )$ and $\backslash (\backslash$mathbf$\{$R$\}\backslash )$ which act at supports $\backslash ($ A $\backslash )$ and $\backslash ($ B $\backslash )$ so that the resultant of the two couples is zero. Note that the support legs of the motor are inclined at an angle $\backslash (\backslash$boldsymbol$\{\backslash$theta$\}\backslash )$ as shown in the diagram below. h$($ft$)=1\mathrm{.}25,$ M$($lbs$-$ft$)=7,$ deg$=75.$
