Couple acting on a beam

    1. The problem statement, all variables and given/known data
    Hi I have a beam that is supported at one end and at the other has a point moment (couple) acting on it at the end point. I was wondering the follwing equation is correct for the moment at any point on the beam.

    M= Cx/L

    Where M is the moment, C is the force of the couple, x is the location where the moment is wanted and L is the length of the beam?

    Why would you think that?

    Draw a shear/moment diagram. (hint, the moment can only vary if there is shear).
