Acenter of gravity

Bcontraflexure

Cmaximum stress

Dmaximum shear stress

Answer:

B. contraflexure

Read Explanation:

The point where the beam's curvature changes from sagging to hogging is called a point of contraflexure. It is a location where the bending moment is zero and the bending moment curve intersects with the zero lines. The equation is M = 0.

When the shear force at a section of a beam under bending is zero, the bending moment at that section is either a maximum or a minimum. This is because the shear force is a measure of the rate of change of the bending moment. When the shear force is zero, the bending moment is either at its peak or at its trough.
Section modulus Z is expressed as
