Simple harmonic motion of a spring

  1. Dec 11, 2007 #1
    1. The problem statement, all variables and given/known data
    A horizontal plank (m = 2.0 kg, L = 1.0 m) is pivoted at one end. A spring
    (k = 1.0 x 10
    3
    N/m) is attached at the other end, as shown in the figure. Find the angular frequency
    (in rad/s) for small oscillations


    2. Relevant equations

    w = (mgd/I)^0.5 I= 1/3 ML^2

    3. The attempt at a solution
    w = (2*9.8*1/ (2/3)

    I'm not sure what you did here. Start by writing the force equation and comparing it to that for a simple mass on a spring.
