Question

The point on the beam where the curvature changes from sagging to hogging is a point of

• A. center of gravity
• B. contraflexure
• C. maximum stress
• D. maximum shear stress

Answer 1

Answer:

B. contraflexure

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.
