In a amusement park ride, gondola cars of weight W are attached by rods 24ft long to a bull wheel 16ft in diameter. The bull wheel rotates in a horizontal plane about a vertical axis at its center. At how many rpm is it rotating when the supporting rods of the gondolas are inclined at 30° with the vertical? Consider each gondola to be a particle concentrated at the end of each 24ft rod.
