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.
(a) Compute the angular acceleration of the wheel and the
acceleration of the part of the cord that has already been
pulled off the wheel. (b) Find the magnitude and direction of
the force that the axle exerts on the wheel. (c) Which of the
answers in parts (a) and (b) would change if the pull wefre
upward instead of horizontal?   Detailed answers to tough
