Torque required to rotate a composite structure

  1. Apr 14, 2010 #1
    Hi everyone I posted this in the classical physics forum but maybe it is more suitable for this forum.

    I'm currently trying to select 2 hydraulic motors to rotate a relatively sizeable structure,

    I'm hoping to rotate it through .5pi radians over a period of 30 mins (0.052 RPM), I'm hoping to rotate it at a relatively constant speed, obviously some acceleration will be required to get it up to speed.

    The structure itself weighs 306 tons and has a moment of inertia of 13.136e6 Kg/m2

    Any Help would be much appreciated
