Determine the shear-force and bending-moment equations for the beam. Then sketch the
diagrams using the aforementioned equations if necessary to ascertain key points in the
diagrams, such as the position between the supports where V=0. What is the bending
moment there?

The following is the figure and how I drew the Free Body Diagram. Remember, I only neglected the Coupled-Forces, not the m0ment they cause.

I found:
W = 180 N
Ay = 60 N
By = 1120 N

No need for the sketching part, I can do that. Just need help with the equations.

Any help is greatly appreciated.

By their nature, simple supports can transmit forces but are incapable of transmitting any moments.

What specific problems are you having with the equations?

What have you tried? Have you started to write anything down?
