Sagging, the bending moment occurs at the _____ of the beam.

Sagging, the bending moment occurs at the _____ of the beam. Correct Answer Mid span

The positive bending moment is considered when it causes convexity downward or concavity at top. This is sagging. In simply supported beams, it occurs at mid span because the bending moment at the supports obviously will be zero hence the positive bending moment occurs in the mid span.
