Solid mechanics, beams

  1. Feb 20, 2010 #1
    Hi,
    In a cantilever beam with a load on the free end, at a point on the neutral axis, will the normal stresses (due to bending stress and axial stress) be zero? Or am i wrong? And if i was to draw a Mohr circle for that point at the neutral axis, would the center of the circle be the origin? Im assuming that because there are only shear stresses at that point.

    Thanks

    Agreed, as long as the long is perpendicular to the beam axis.
