1. Determine the moment of inertia of a 4-kg disk with 12-cm radius 2. Determine the moment of inertia of a 4-kg ring with a 10-cm inner radius and a 12-cm outer radius. Notice that even though both objects have the same mass and the same outer radius, they have different moments of inertia because their shapes are different! The ring will resist more when we try to change its angular velocity than the disk will.

A string is wrapped around a uniform disk of mass M = 2.2 kg and radius R = 0.1 m. (Recall that the moment of inertia of a uniform disk is (1/2) MR2.)
A string is wrapped around a uniform disk of mass M = 2.2 kg and radius R = 0.1 m. (Recall that the moment of inertia of a uniform disk is (1/2) MR2.) Attached to the disk are four low-mass rods of radius b = 0.13 m, each with a small mass m = 0.7 kg at the end. The device is initially at rest on a nearly frictionless surface. Then you pull the string with a constant force F...

Lab 8 Assignment: Moment of Inertia 1) Moment of Inertia for Different Systems The resistance to rotational motion change is more involved than for linear motion because it not only depends on what the mass is, but also on how that mass is distributed about the axis of rotation. The farther away from the axis the mass is distributed, the greater the moment of inertia. Using this simple definition, for each of the following pairs of objects, determine which of...

Suppose we want to calculate the
moment of inertia of a 67 kg skater, relative to a vertical axis
through their center of mass.
Part (a) First calculate the
moment of inertia (in kg⋅m2) when the skater has their
arms pulled inward by assuming they are cylinder of radius 0.11 m.
Part
(b) Now calculate the moment of inertia of the skater (in
kg⋅m2) with their arms extended by assuming that each
arm is 5% of the mass of their...

Question 3 10 pts A horizontal disk with moment of inertia 0.36 kg-m2 is rotating with an angular speed of 6.5 rad/sec. A point mass of 0.52 kg is gently placed on the outer edge of the disk in a manner so that no torque is applied. The mass then rotates with the disk at an angular speed of 4.37 rad/sec.

Find the uncertainty in the moment of inertia. Moment of interia of a disk depends on mass and radius according to this function I(m,r) = 1/2 m r2. Your measured mass and radius have the following uncertainties delta m space equals space 0.43 kg and delta r space equals space 0.11 m. What is is the uncertainty in moment of interia, delta I , if the measured mass, m = 6.43 kg and the measured radius, r = 10.14 m?
