I have a problem involving a hand crank, an axle, and a bucket. The crank turns the axle. The axle lowers the bucket. When someone spins a hand crank, the angular velocity of the hand crank and the axle are the same right? I think it and they seem to be the same. The velocity of the bucket equals the linear velocity of the axle. Correct. Sorry if my English isn't good as it is not my first language.
