Under a point load (W) at the free end, why would a cantilever beam of length L have a pressure at the free end (θB)?
(E is Young's modulus and । is the moment of inertia)
1
\(\theta_{B}=\frac{W L^{2}}{2 E I}\)
2
\(\theta_{B}=\frac{W L^{2}}{16 E I}\)
3
\(\theta_{B}=\frac{W L^{2}}{8 E I}\)
4
\(\theta_{B}=\frac{W L^{2}}{4 E I}\)
