Cantilever Beam Q

Q: If you have a cantilever beam (which means its embedded in a wall and sticking out with the other end completely free) and it has a uniform load applied to it, where along this beam (point A to B) is it experiencing the maximum amount of internal bending stress?

A: The maximum stress from bending is felt the most at Point A, because a free end (Point B) experiences 0 internal stress due to bending allthe stress is at Point A and gradually decreasing to the end of point B.

Shear diagram showing sum of all forces in the y direction F_y = 0 that would mean A^{_{y (}}force at A) - all the force across the span (200N/m) multiplied by the span length (10m) to = 0 then move everything to one side making A = 2000N which is the reaction force.

Moment diagram showing that sum of all moments around point A = 0 then there is an internal moment at point A (M_a) - (minus because its looking from point B to Point A which is the opposite direction) 200N/m x 10m and all of that force can be modelled as a point load right in the center (halfway across the beam) so multiply by half the span (5m) and all that rotation has to add up to 0. This results in a moment of 10,000Nm at the beginning of point A.
