For a prismatic beam of length 'L' and flexural rigidity EI, the moment required to rotate the near end through unit angle, whose far end is fixed, will be
1
\(\frac{{6{\rm{EI}}}}{{\rm{L}}}\)
2
\(\frac{{3{\rm{EI}}}}{{\rm{L}}}\)
3
\(\frac{{2{\rm{EI}}}}{{\rm{L}}}\)
4
\(\frac{{4{\rm{EI}}}}{{\rm{L}}}\)
