Flexural strength of triangular prism

  1. Oct 9, 2015 #1
    Hello forum,

    could someone share a formula to calculate the flexural strength and flexure modulus of a beam with a rounded triangular cross-section?

    Namely triangular crayons, which is rounded on the edges.
    Assuming that the triangle is equilateral.
