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 the center increases by an amount 5 x 10-4 kg.m2/s. What is the magnitude of each force?

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 thin rod of mass m and length l rests on a frictionless table and is struck at a point l/4 from its center of mass by a clay ball of mass m moving at speed v.
A thin rod of mass m and length l rests on a frictionless table and is struck at a point l/4 from its center of mass by a clay ball of mass m moving at speed v. The ball sticks to the rod. If the rod is free to pivot about a frictionless pin at its center, find the angular velocity of the rod after the collision. Also find the velocity of the point at the top of the rod...

a uniform rod of mass1 = 4.7 kg and legth 80 cm lies horizontal frictionless table, with a vertical frictionless axle passing through a point P, located 25cm from center of mass of the rod. Also a particle of mass 2 = 1.2 kg is attached to the rod 5 cm from the far end. A. Find the moment of inertia of the rod only about point P. The system is initially rotating counter clock wise about P at 6.40...

1. A thin rod of mass M and length d hangs vertically from a frictionless pivot attached to one end. A piece of clay of mass m moving horizontally at a speed v hits the rod a distance x from the pivot and sticks to it. Discussion Questions: (In the first 5-10 min a random group will be selected to explain.) • What “type” of collision is happening? What is and is not conserved? • Consider the analogous linear momentum...
A uniform wheel of mass 10.0 kg and radius 0.400 m is mounted rigidly on an axle through its center
A uniform wheel of mass 10.0 kg and radius 0.400 m is mounted rigidly on an axle through its center (see figure . The radius of the axle is 0.200 m, and the rotational inertia of the wheel-axle combination about its central axis is 0.600 kg·m2. The wheel is initially at rest at the top of a surface that is inclined at angleθ = 43.6o with the horizontal; the axle rests on the surface while the wheel extends into a...

Two small objects each of mass m = 0.2 kg are connected by a lightweight rod of length d = 1.5 m (see the figure). At a particular instant they have velocities whose magnitudes are v_1 = 36 m/s and v_2 = 50 m/s and are subjected to external forces whose magnitudes are F_1 = 63 N and F_2 = 26 N. The distance h = 0.4 m, and the distance w = 0.6 m. The system is moving in...
