Multiple choice

The following statements are related to bending of beams: I. The slope of bending moment diagram is equal to the shear force II. The slope of the shear force diagram is equal to the load intensity. III. The slope of curvature is equal to the flexural rotation. IV. The second derivative of the deflection is equal to the curvature. The only FALSE statement is

  1. I

  2. II

  3. III

  4. IV

C Correct answer
Explanation

Statement III is false. The slope of the deflection curve is the rotation, and the curvature is the second derivative of deflection. The slope of curvature is not flexural rotation.
