Rotation of Rigid bodies

  1. Jul 28, 2009 #1
    1. The problem statement, all variables and given/known data

    A cord is wrapped around the rim of a solid uniform wheel 0.250 m in radius and of mass 9.20 kg. A steady horizontal pull of 40.0 N to the right is exerted on the cord, pulling it off tangentially from the wheel. The wheel is mounted on frictionless bearings on a horizontal axle through its center. Find the magnitude and direction of the force that the axle exerts on the wheel

    2. Relevant equations
    Newtons laws

    3. The attempt at a solution
    I understand that there are normal force and weight along y-axis. However i'm confused whether there is any x-component force exerted by the axle on the wheel. Kindly explain me??

    I might be wrong as I haven't reached this subject matter just yet, but I think you need to take into consideration the fact that there is 0 linear translation of the center of mass.

    Another force is suddenly required.

    The center of mass isn't moving, what does that say about the net force acting on the mass?
