How to find moment?

    how to find bending moment?
    information given : distance= 0.9m
    with SFD and BMD diagram...and the cross section
    but the moment equation is not given...so how to find the bending moment at x= 0.9m?

    If you're given the bending moment diagram, it's just a case of going to 0.9m on the x-axis and reading off the corresponding bending moment.

    the problem is...the graph is not in scale...
    it is just a sketch.

    Hmmmmm, well, the bending moment is force x distance so you need to find the force at the point of interest.....can you post the full question?

    Of course it is. It is probably to help or test your understanding of BM diagrams.

    Don't forget that the 'sketch' will be a straight line or a parabola and that you can locate exactly the break and zero points. Once you have these you can calculate what happens at other points.
