Flexural rigidity of a cantilever beam is EI. A load P and bending moment of PL/2 is applied at the free end of the beam as shown in the figure. The length of the beam is L. Slope at the free end of the beam is
1
\(\frac{PL^2}{2EI}\)
2
\(\frac{5PL^2}{2EI}\)
3
\(\frac{3PL^2}{2EI}\)
4
\(\frac{PL^2}{EI}\)
