Question

A beam of length L is carrying a uniformly distributed load w per unit length. The flexural rigidity of the beam is EI.The reaction at the simple support at the right end is

• A. $wL/2$
• B. $\frac{3wL}{8}$
• C. $wL/4$
• D. $wL/8$

Answer 1

The correct option is B $\frac{3wL}{8}$



Deflection at the support is zero,
$\delta =\frac{-w{L}^4}{8EI}+\frac{R{L}^3}{3EI}=0$
$R=\frac{3wL}{8}$
