The $\backslash (63-\backslash$mathrm$\{$kg$\}\backslash )$ gate has a center of mass located at $\backslash ($ G $\backslash ).$ If $\backslash ($ A $\backslash )$ supports only a horizontal force and $\backslash ($ B $\backslash )$ can be assumed as a pin, determine the components of reaction at these supports. $($Eigure $1)$

Figure

Part A

Determine the force of reaction at support $\backslash ($ A $\backslash ).$

Express your answer to three significant figures and include the appropriate units. Assume that the positive $\backslash ($ x $\backslash )$ and $\backslash ($ y $\backslash )$ axes are directed to the right and upward, respectively.

Part B

Determine the components of reaction at support $\backslash ($ B $\backslash ).$

Express your answers using three significant figures separated by a comma. Assume that the positive $\backslash ($ x $\backslash )$ and $\backslash ($ y $\backslash )$ axes are directed to the right and upward, respectively.
