Deflections on curved beam

  1. Oct 26, 2015 #1
    1. The problem statement, all variables and given/known data
    Working out deflections on a semi circular bar.

    2. Relevant equations
    3WR^3π / 2EI

    Where E = 200GN/m^2
    W = 9.81N
    R = 150mm
    I = 5.625 * 10^-3 (bar is 25mm * 3mm)

    3. The attempt at a solution
    (3)(9.81)(0.15)^3π / (2)(200*10^3)(5.625 * 10^-3) = 13868.56

    I have data that says it should be more like
    1.3870359

    I'm not exactly sure of the units either?

    Heck, we're not even sure what the problem is.

    Is there a figure or some other description of what you are trying to solve? Is this bar laterally loaded? Is it a point load? Distributed load? Are the ends both fixed?

    The semi circle bar is fixed at one point and has a point load at the other end.

    Maybe you can insert a picture?
