Current Attempt in Progress

The shaft, lever, and handle are welded together and constitute a single rigid body. Their combined mass is $30$ kg with mass center at $G.$ The assembly is mounted in bearings A and $B,$ and rotation is prevented by link CD$.$ Determine the magnitudes of the fofces exerted on the shaft by bearings A and $B$ while the couple is applied to the handle as shown. Would these forces change if the couple were applied to the shaft $AB$ rather than to the handle?
