if you look at the attached photo.

we have 2 beams, 1) is shorter, 2) is longer. cross-sectional area is the same. same force is applied X cm from the fixed end.

what is the max stress in each case? why are they the same ( and why not)?

Take gravity out of the equation.
FEA shows differnt result.
