Bending moment for curve and straight beam

  1. Aug 7, 2012 #1
    It’s clear that bending moment for a curve beam is less than straight one
    And you can attribute this to moment of inertia, but there is something i don’t understand
    Which is if i have straight beam with small moment of inertia or huge moment of inertia simple supported beam), the moment will not differ, so why it will differ in curve beam.

    Are you confusing bending stress with bending moment? Bending moment is a function of load and distance and has nothing to do with moment of inertia. Bending stress is dependent on the moment of inertia.
