Calculating maximum bending stress in an I beam?

  1. Nov 26, 2013 #1
    Hello all, I am confused on how to calculate the maximum bending stress in an I-beam.

    I found the maximum deflection in each beam where the load is placed at the center of the span.

    I also know all the cross-sectional dimensions of the I-beam.

    Is it now possible to calculate it?

    Thanks

    First of all, do you know the maximum bending moment on the beam? Do you know how to calculate bending stress?

    Maximum Bending Stress can be found using flexural formula (σ/y)= (M/I) where σ is bending stress, y is distance of outermost fibre from the Neutra axis, M is maximum Bending moment and I is the Moment of Inertia.
