Mounted on a low-mass rod of length 0.52 m are four balls. Two balls (shown in red on the diagram), each of mass 0.92 kg, are mounted at opposite ends of the rod. Two other balls, each of mass 0.23 kg (shown in blue on the diagram), are each mounted a distance 0.13 m from the center of the rod. The rod rotates on an axle through the center of the rod (indicated by the "x" in the diagram), perpendicular to the rod, and it takes 1.4 seconds to make one full rotation. (a) What is the moment of inertia of the device about its center? I = kg-m2 (b) What is the angular speed of the rotating device? W = radians/s (c) What is the magnitude of the angular momentum of the rotating device? | kg-m²/s

One end of a thin, uniform rod is connected to a frictionless hinge as shown in the figure below (Figure 1). The rod has a length of 0.8 mm and a mass of 2 kgkg. It is held up in the horizontal position (θ=90∘�=90∘) and then released. Calculate the angular velocity of the rod at θ=0∘�=0∘.
Mounted on a low-mass rod of length 0.32 m are four balls (see figure below). Two balls (shown in red on the diagram), each of mass 0.83 kg, are mounted at opposite ends of the rod. Two other balls, each of mass 0.31 kg (shown in blue on the diagram), are each mounted a distance 0.08 m from the center of the rod. The rod rotates on an axle through the center of the rod (indicated by the " X " in the diagram), perpendicular to the rod, and it takes 0.9 s to make one full rotation.

Imagine a meter stick set up as in the figure (in the video above). It hangs from a central bracket, and two hanging masses can hang from it from each of their brackets. At a third location, a force probe can either pull up or pull down on the stick, depending on what is needed to balance the stick. The mass of the meter stick is 120 g. sketch the situation (drawing r1, r2, r3, F1, F2, and F3) and determine the magnitude (value) and direction (+ or -) of each torque. Remember that the x value given in the table is the position of the hanging mass, but that might be different from the r value you need to use. Don't include the mass of a bracket that would hold the hanging mass in place; assume the mass listed is the entire mass hanging at that point.
