Homework Help: Period of Vibration of Torsion Pendulum

  1. Dec 12, 2015 #1
    1. The problem statement, all variables and given/known data
    Given the period (T) and the moment of inertia (I), find the Torsion constant (K)
    T= 1.32s
    I= 0.0383 kgm^2
    2. Relevant equations

    3. The attempt at a solution
    The answer is K=0.8678, i'm not really sure how to get the answer, but I think it has to do with the units.

    That's a big equation! :-)

    Are you at ease with algebra? You just need to plug in the values of T and I in the formula and then solve for K.
