Engineering mechanics problem about shear and moment in beams

  1. Jan 29, 2012 #1
    fresh out of ideas. Need help.
    1) Solve for shear and moment at the given distances
    a) at midspan
    b) 5m from ROLLER "A"

    SO FAR I GOT THE REACTIONS AT POINT A AND B. 13KN AND 15.5KN RESPECTIVELY
    2) Solve for shear and moment at the given distances
    a) 5m from ROLLER "A"
    b) 9m from ROLLER "A"
    SO FAR I GOT THE REACTIONS AT POINT A AND B. 5.525N AND 22.475N RESPECTIVELY

    Hint on probem A for shear: Write an expression for the shear force starting from point A and moving to the right. You have the reaction at A as 13KN. So at point A the shear force is the upward reaction force, 13N. Beginning at point A you have a varying downward load. It would be the product of the distributed load function and the distance from point A that is of interest. Combine for shear at any point of interest.

    The moment is handled in analogous fashion.
