A simply-supported beam of length l carries two equal unlike couples M at two ends. If the flexural rigidity EI = constant, then the central deflection of the beam is given by
1
\(\frac{{{\rm{M}}{{\rm{l}}^2}}}{{4{\rm{EI}}}}\)
2
\(\frac{{{\rm{M}}{{\rm{l}}^2}}}{{64{\rm{EI}}}}\)
3
\(\frac{{{\rm{M}}{{\rm{l}}^2}}}{{16{\rm{EI}}}}\)
4
\(\frac{{{\rm{M}}{{\rm{l}}^2}}}{{8{\rm{EI}}}}\)
