Question

A uniform cantilever beam of length L and flexural rigidity EI is loaded by a force F as shown in the figure. Assuming that the Euler-Bernoulli beam theory is applicable here, the magnitude of the static deflection at the free end of the beam is

• A. $\frac {FL^3}{(6EI)}$
• B. $\frac {14FL^3}{(81EI)}$
• C. $\frac {5FL^3}{(27EI)}$
• D. $\frac {27FL^3}{(48EI)}$

Answer 1

Answer: (B)

$\frac {14FL^3}{(81EI)}$

Answer 2

The correct option is (B): $\frac {14FL^3}{(81EI)}$.
