Question

A simply supported beam of span L shown in the below figure is subjected to a concentrated load W at its mid - span and also to a uniformly distributed load equilvalent to W. It has a flexural rigidity of EI. What is the total deflection at its mid -point ?

• A. $\frac{5}{384}\frac{W{L}^3}{EI}$
• B. $\frac{9}{384}\frac{W{L}^3}{EI}$
• C. $\frac{13}{384}\frac{W{L}^3}{EI}$
• D. $\frac{18}{384}\frac{W{L}^3}{EI}$

Answer 1

The correct option is B $\frac{9}{384}\frac{W{L}^3}{EI}$

Three moments equation is used to determine moments.
