Two identical beams are fixed to a wall at A and B, respectively.A 30 lb force is supported at E by a single weightless cable CD.Cable CD is attached to the two beams at nodes C and D.Assume the geometry is known and the beams are weightless

When drawing the free-body diagram of beam BD, how many reaction forces/moments should be drawn at B? Assume the reaction forces/moments are split into Cartesian components.

Whiledrawing the free-body diagram of beam BD, reaction forces/moments should be drawn at B.
