A cantilever of span ‘l’ carries a load ‘W’ at the free end. The flexibility of the beam is given by:
1
\(\frac{{{{\rm{L}}^2}}}{{3{\rm{\;EI}}}}\)
2
\(\frac{{{{\rm{L}}^3}}}{{3{\rm{\;EI}}}}\)
3
\(\frac{{\rm{L}}}{{3{\rm{\;EI}}}}\)
4
\(\frac{{{{\rm{L}}^3}}}{{8{\rm{\;EI}}}}\)
5
\(\frac{{{{\rm{L}}^2}}}{{2{\rm{\;EI}}}}\)
