A cord is wrapped around the rim of a solid uniform wheel 0.230 meter in radius and of mass 9.60 kilogram. A steady horizontal pull of 48 Newton 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.
Determine the angular acceleration of the wheel.
Find the acceleration of the part of the cord that has already been pulled off the wheel.
Compute the magnitude of the force that the axle exerts on the wheel.
Determine the direction of the force that the axle exerts on the wheel.
