19–33. The 80-kg man is holding two dumbbells while
standing on a turntable of negligible mass, which turns
freely about a vertical axis. When his arms are fully
extended, the turntable is rotating with an angular velocity
of 0.5 rev/s. Determine the angular velocity of the man
when he retracts his arms to the position shown. When his
arms are fully extended, approximate each arm as a uniform
6-kg rod having a length of 650 mm, and his body as a 68-kg
solid cylinder of 400-mm diameter. With his arms in the
retracted position, assume the man is an 80-kg solid cylinder
of 450-mm diameter. Each dumbbell consists of two 5-kg
spheres of negligible size.
