    Reaction Forces - Bending Moment Diagram - Shear Force Diagram

    Hello all


    I was hoping i could get some support on calculating re-action forces and creating a shear force and bending moment diagram.

    Some of the examples i have worked on relate to a beam supported at either end.

    But the example below has gotten me a little confused.

    I have a 21m member that is supported at 4 points along the member spaced 7m apart. The member is UDL loaded with 200kN/m. (assumed no horizontal forces).

    I can work out an equivalent point load of 4200 acting at the center on the member (10.5m from the ends).

    Not sure what to do from here?

    Can anyone help?

    Thanks
