Hi all,
I was thinking when we draw tension/compression side of beam stress diagram? Attached below is a simple beam subjected to Uniform DL and Point load. This is longitudinal stress (S11) and tension is at top drawn, while compression side is drawn at bottom. Why tension side is drawn at top?Is this due to max moment is negative, hence top is tension and bottom compression (when sigma = Mc/I). Because the load is applied and the fibres of beam supposed to go undergo tension at bottom. Any clarifications is appreciated.
Cheers
