Calculating the moment along a statically indeterminate beam

  1. Dec 8, 2013 #1
    1. The problem statement, all variables and given/known data

    How could I calculate the piecewise formula for M(x)?

    2. Relevant equations

    3. The attempt at a solution

    From constructing a free body diagram it looks like up until the pin support, M(x) = -Fy*x (Fy being the force pointing upwards at the wall) but I am confused about how to handle the moment at the end in this calculation. Unfortunately the course I am taking assumes I already know how to do this, so I don't have a textbook or anything to rely on.
    Thanks for any help you can give me.

    Think about what the moment diagram looks like at the RHS of the beam with M0 applied there.

    In these types of problems, it helps to draw a free body diagram and put in all of the reactions and moments which occur at the supports.
