    Taking Moments Propped Cantilever

    Hello all

    I was hoping someone could shed some light on the following question:-

    I have a propped cantilever beam as shown below:-

    I want to work out the vertical reactions at support A and B.

    I have been told to work out the vertical reactions I need to take moments about support B and by doing so the reactions at support B "disappear" - my question is if I take moments about support B do ALL of the reactions disappear and if not which ones remain and which ones disappear?

    I hope this makes sense.

    Thank you.

    Tell me and I forget. Teach me and I remember. Involve me and I learn.
