Mechanical Engineering Statics

For the structure shown in Fig $1,$

$1)$ Find reactions at support A and B $($need to show FBD$)$

$2)$ If the couple moment is reversed, but still $800$ lb$-$ft$,$ will the beam be lifted from location A$?($Need to show the detail calculations$).$

$3)$ What is the maximum magnitude of the reversed couple moment without causing to lift the beam from A$.$
