Which of the following equations is the correct expression for shear force (V) in an element, given the modulus of elasticity (E), moment of inertia (I), element length (le), displacement (q) in a uniformly distributed load on a simply supported beam?

A. V= ( frac{EI}{(le)^3} )(2q<sub>1</sub>+l<sub>e</sub>q<sub>2</sub>-2q<sub>3</sub>+l<sub>e</sub>q<sub>4</sub>)
B. V= ( frac{EI}{(le)^2} )(2q<sub>1</sub>+l<sub>e</sub>q<sub>2</sub>-2q<sub>3</sub>+l<sub>e</sub>q<sub>4</sub>)
C. V= ( frac{EI}{(le)^2} )(2q<sub>1</sub>+l<sub>e</sub>q<sub>2</sub>+2q<sub>3</sub>+l<sub>e</sub>q<sub>4</sub>)
D. V= ( frac{EI}{(le)^3} )(2q<sub>1</sub>+l<sub>e</sub>q<sub>2</sub>+2q<sub>3</sub>+l<sub>e</sub>q<sub>4</sub>)
Answer» B. V= ( frac{EI}{(le)^2} )(2q<sub>1</sub>+l<sub>e</sub>q<sub>2</sub>-2q<sub>3</sub>+l<sub>e</sub>q<sub>4</sub>)
