Basic equation of deflection (y) of the beam is represented by \(EI\frac{{{d^2}y}}{{d{x^2}}} = M\), where EI → flexural rigidity and M → Bending moment, then \(EI\frac{{{d^3}y}}{{d{x^3}}}\) will be:

A. Rate of loading
B. Shear force at the section
C. Bending moment at section
D. Zero always
Answer» C. Bending moment at section
