Where is the exact location of the maximum tension bending stress for the following beam, assuming the BMD is drawn to scale and the cross section is symmetrical?
Remember the positive axis for beam bending is vertically down down and a positive moment equates to the beam have a sagging/concave deflected shape while a negative moment equates to the beam have a hogging deflected shape.
