Angular Momentum Vector and Precession
A disk with mass m = 6.1 kg and radius R = 0.39 m hangs from a rope attached to the ceiling. The disk spins on its axis at a distance r = 1.51 m from the rope and at a frequency f = 19.8 rev/s (with a direction shown by the arrow).1)What is the magnitude of the angular momentum of the spinning disk?2)What is the torque due to gravity on the disk? if found this to be --> 90.2678...

1. A gyroscope consists of a rotating disk with a 25 cm radius suitably mounted at the midpoint of a 20 cm long axle so that it can spin and precess freely. One end is supported by a stand. The disk spins at 2000 rpm. The mass of the disk is 2 kg, and the axle can be taken as massless. a. Draw the gyroscope, indicating the direction of the initial angular speed and the initial angular momentum. Choose a...

Up A #4. [Gyroscope Wheel] A rubber wheel on a steel rim spins freely on a horizontal axle that is suspended by a fixed pivot at point P. When the wheel spins at a rate of 4.00 rev / s, it precesses smoothly about point Pin a horizontal plane with a period of 3.50 s. The wheel's outer radius is 15.0 cm, and it's total mass is measured to be 1.12 kg, 60% of this being the spinning wheel and...

What is the angular kinetic energy of the Earth due to its orbit around the sun?...
What is the angular kinetic energy of the Earth due to its orbit around the sun? In Homework 10, you found the two main angular velocities of the Earth: one due to the Earth's motion around the sun, and one due to its rotation about its own axis. Now let's figure out the energy and momentum associated with that motion. IVO ALV O a ? For the purposes of this problem, treat the Earth as a solid, uniform sphere with...

Calculate the angular momentum for a rotating disk, sphere, and rod. (a) A uniform disk of mass 16 kg, thickness 0.5 m, and radius 0.9 m is located at the origin, oriented with its axis along the y axis. It rotates clockwise around its axis when viewed from above (that is, you stand at a point on the +y axis and look toward the origin at the disk). The disk makes one complete rotation every 0.7 s. What is the...
