A barbell consists of two small balls, each with mass 500 grams
(0.5 kg), at the ends of a very low mass rod of length d= 20 cm
(0.2 m). The center of the barbell is mounted on the end of a low
mass rigid rod of length b= 0.3 m (see Figure). The apparatus is
started in such a way that although the rod rotates clockwise with
angular speed 80 rad/s, the barbell maintains its vertical
orientation.

A barbell is mounted on a nearly frictionless axle through its center. The low-mass rod has a length d= 0.16 m, and each ball has a mass m = 0.1 kg.
A barbell is mounted on a nearly frictionless axle through its center. The low-mass rod has a length d= 0.16 m, and each ball has a mass m = 0.1 kg. At this instant, there are two forces of equal magnitude F applied to the system as shown, with the directions indicated, and at this instant the angular velocity is 60 radians/s, counterclockwise, and the angle α = 20 degrees. In the next 0.003 s, the angular momentum relative to...
