Question

At a certain section at a distance 'x' from one of the supports of a simply supported beam, the intensity of loading bending moment and shear force are $w_x,M_x$ and $V_x$ respectively. If the intensity of loading is varying continuously along the length of the beam then the invalid relation is

• A. ${\theta }_x=\frac{M_x}{V_x}$
• B. $V_x=\frac{d{M}_x}{dx}$
• C. $w_x=\frac{d^2{M}_x}{d{x}^2}$
• D. $w_x=\frac{d{V}_x}{dx}$

Answer 1

The correct option is A ${\theta }_x=\frac{M_x}{V_x}$

Slope , ${\theta }_x=\frac{1}{EI}\int Mdx$
