Simple column buckling problem - pl help!

  1. Dec 25, 2009 #1
    Knowing that the torsional spring is of constant K and that the rigid bar is of length L, determine the critical load [TeX]P_{cr}[/TeX] beyond which the column would buckle. See pic for the problem.
    [As the spring uncurls, it applies moment [TeX]K \theta[/TeX] to the bar.]


    The answer is [tex]P_{cr}=K/L[/tex]
