Homework Help: Shear Moment Diagram

  1. Feb 28, 2007 #1
    1. The problem statement, all variables and given/known data
    Find the shear and moment diagram.

    2. Relevant equations

    dV/dt = -w(x)

    dM/dt = V(x)

    3. The attempt at a solution
    See attached.

    My problem is that I'm getting 0.06 kip*ft at the end of the beam, and I don't think that's right.

    Can you explain you're work. The images don't show up too well, and i don't see alot of work explaining the graphs. I'm familiar with the method you're using, guess you could call it a short-cut.

    Also you can try going through the problem again using the differential equations that you provided. It's a little more work with getting the boundary conditions, but you should get the same answer.

    Nothing to add that teknodude didn't already say, but I suggest you use a different bending moment sign convention, since a minority of people sketch bending moment/shear force diagrams like this. But then again, if you were explicitly taught to do it like that, no problemo.
