Question

The maximum deflection of a fixed beam carrying a central load W is equal to

• A. $\frac{W{L}^3}{484EI}$
• B. $\frac{W{L}^3}{96EI}$
• C. $\frac{W{L}^3}{192EI}$
• D. $\frac{5}{384}\frac{W{L}^3}{EI}$

Answer 1

The correct option is C $\frac{W{L}^3}{192EI}$

The centre point deflection of fixed beam carrying central load is one -fourth of the centre point deflection od simply supported beam carrying point load.

$\therefore \delta =\frac{1}{4}\left(\frac{W{L}^3}{48EI}\right)=\frac{W{L}^3}{192EI}$
