Hello guys,
I have a simple question about the max bending stress in a beam.
We know that in a cantilever beam, the biggest moment occurs at the wall. This is also the location of the max stress with equation stress= M*y/I
,
However, in a simple supported beam, we have
This time, the max moment occurs at the middle of the beam. But I doubt this is the location of the max stress. I think the max stress location should still be at the wall.
So we have a problem here: Is the max bending stress located at the location of the moment?
