A train traveling at a constant speed rounds a curve of radius 200 m. A chandelier suspended from the ceiling swings out to an angle of 16.5° throughout the turn. What is the speed of the train?

Form the force diagram.
Force on the chadelier will have the centripetal force component (outward) and the gravity component (downward)
tan 16.5deg = v^2 / ( r * g )
=> v = sqrt( 200 * 9.8 * tan 16.5deg )
=24.1 m/s

b. A pail of water on the accurate of a rope swung in a round action with the rigidity on the rope providing thecentripetal acceleration of the bottom of the pail antagonistic to the water to maintain it from falling on the guy swinging the pail of water. See the 2009 Yahoo concepts contained contained in the source.
