Question 6 5 pts A giant fidget spinner is made up of a solid disk (i.e....
b. Refer to the drawing here. A solid, uniform disk has a mass of M and outer radius R. A heavy metal bolt of mass m is attached to the disk at a point that is located a distance r from the disk's center The bolt and the disk center lie along one diameter across the disk. Consider a second diameter that is perpendicular to the one containing the bolt; and let point P be located at one end of...
4. b. Refer to the drawing here. A solid, uniform disk has a mass of M and outer radius R A heavy metal bolt of mass m is attached to the disk at a point that is located a distance r from the disk's center. (overhead view) R: The bolt and the disk center lie along one diameter across the disk. Consider a second diameter that is perpendicular to the one containing the bolt; and let point P be located...
1. A piece of laboratory equipment consists of a solid disk (the gray pulley) with a mass of 0.126 kg and a radius of 0.111 m, a rod (mass 0.193 kg, length 0.631 m) pivoted about its center, plus two "point" masses (eåch 0.108 kg) attached to it so each is a distance of 0.217 m from the center pivot. See drawing. For rotation about the center pivot point... A) ... what is the moment of inertia of the solid...
Question 25 3 pts Tim 1 He An object is made out of a 2.0 kg disk of radius 15 cm and four, 5.0-cm radius disks, each with mass 0.25 kg. The small disks are attached symmetrically to the outer edge of the bigger disk, as shown. The object rotates about an axis through its center that points in and out of the page, and that is also perpendicular to the disk. What is the moment of inertia of this...

Question 9 4 pts Suppose a disk of radius R = 6 cm is rotating with an angular velocity w = 7 rad/s. What is the speed of a point on the rim of the disk? 200 m/s O 0.84 m/s 14 m/s - 168 m/s O 42 m/s O 0.42 m/s 1.68 m/s 0.06 m/s 0.72 m/s Question 10 4 pts Suppose the angular velocity of a disk of radius R = 6 cm increases uniformly from 14...
10 pts Question 8 Am 1= 24.0-kg object and a m 2 = 6.0-kg object are suspended, joined by a cord that passes over a pulley with a radius of R= 10.0 cm and a mass of M = 3.60 kg as seen in the Figure. The cord has a negligible mass and does not slip on the pulley. The pulley rotates on its axis without friction. The objects start from rest d = 4.20m apart. Treat the pulley as...
Question 5. Consider the following four obiects: a hoop, a flat disk,a solid sphere, and a hollow sphere. Each of the objects has mass M and radius R. The axis of rotation passes through the center of each object, and is perpendicular to the plane of the hoop and the plane of the flat disk. Which of these objects requires the largest torque to give it the same angular acceleration? A) the hoop D) the flat disk B) the hollow...
