Homework Help: Angular Velocity Question

  1. Jun 24, 2008 #1
    1. The problem statement, all variables and given/known data

    q2.jpg


    2. Relevant equations

    w = 2PI f

    v = wr

    Time = 2PI R/V

    3. The attempt at a solution

    w = (2000/PI x 60) x 2PI = 66.66 Radians/Sec

    V = wr = 66.6 x 300 = 19998 ( Is this velocity of the winding drum)

    19998/200 = 99.99 ( Velocity/200 reduction gearbox, gives me the velocity of the motor?)


    Help Appriciated.

    The centripetal force was also given, but you didn't write down the corresponding formula...
