Question

Moment of inertia in bending strength formula

Answer 1

This special form of the flexure formula can only be used to find the maximum bending stress, and uses the section modulus, where the section modulus is equal to themoment of inertia of the beam cross section divided by the maximum distance from the neutral axis of the beam to an outer edge of the beam.

hope it helps!!

Answer 2

the property of matter by which it retains its state of rest or its velocity along a straight line so long as it is not acted upon by an external force. an analogous property of a force: electric inertia.
