Homework Help: ROtate construction

  1. Nov 7, 2009 #1
    1. The problem statement, all variables and given/known data

    I want to calculate the torque of the construction or the needed Power (Watt) to rotate it. The construction is a tube and on top of tube is stuck a rectangular parallelepiped:


    inner diameter=d=92mm, outter diameter=D=102mm, lenght=L=3000mm, mass=12.34kg

    Rectangular parallelepiped:

    x=3000mm, y=5000mm, z= 50mm, mass=250kg

    ...........Please assume missing data if needed..............

    2. Relevant equations

    3. The attempt at a solution

    I dont know exactly because I am messed. I thought about Moment of Inertia or loads.
