Point where BM (Bending Moment) changes between compression and tension or vice versa is known as: Correct Answer Point of Contra flexure

Concept:

  • In a bending beam, a point is known as a point of contra flexure if it's a location at which no bending occurs.
  • In a bending moment diagram, it is the point at which the bending moment curve intersects with the zero lines.
  • In other words where the bending moment changes its sign from negative (compression) to positive (tension) or vice versa.
  • A point of contra flexure occurs in the overhanging beam.
