Homework Help: Antenna torque requirement

  1. Jun 29, 2011 #1
    Hello friends....
    I have an small antenna( irregular shape) , mass about 1.5 Kg (about CG), the moment of ineria about spinning axes(Iyy) is 0.0255kg.m^2. product of inertia also known (Ixy, Iyz, Ixz).
    Required angular velocity (w) = 50 deg/sec
    angular acceleration (a) = 400 deg/sec^2
    The rotation axes is 3mm away from the CG of the antenna. If want to rotate the antenna in the both the direction for every 1hr. How to find the torque and power requirement to rotate it.
    Please any suggestions.......

    Thanks in advance
