Homework Statement
https://en.wikipedia.org/wiki/Bending
[/B]
form the link, we know that σ represent the bending stress, I'm wondering can I call the bending stress as normal stress act at the cross sectional area of beam?
Homework Equations
The Attempt at a Solution
IMO, they are not the same...Because the normal stress act on the cross sectional of beam will only cause the beam to elongate or shorten, it will not cause it to bend , so they are not the same...
