The experimental determination of the moment of inertia is only valid if friction is negligible. In Part III of the experiment, an estimate of the angular acceleration due to friction is obtained. The validity of the above approximation is the examined. Theory, Part I. Consider a pulley made of four disks. The moment of inertia of a homogeneous

(Remember that angular momentum is a vector quantity, it changes when the direction or plane of rotation changes, not only when the angular speed changes.) C. Quantitative Questions: As the student moves in from the rim his moment of inertia changes and so the total moment of inertia of the system (platform + student) changes.

*11-62. Consider Fig. 11-15 in which m = 2 kg, M = 8 kg, R = 60 cm, and h = 6 m. Write Newton’s second law for the disk in terms of the tension in the rope, the moment of inertia of the disk, and the angular acceleration. Next write Newton’s second law for falling mass in terms the tension in the rope, the mass, and the linear acceleration.

The net torque and the angular acceleration are related by a constant. The constant I is called the moment of inertia. The units of the moment inertia are kgm2. The moment of inertia is different for different objects; it depends on how mass of the object is distributed and the …

We will calculate the moment of inertia I. of a disk by applying a torque ( to the disk causing it to have an angular acceleration (. If a force Ft is applied tangentially to the step pulley of radius r, found on top of the disk, the disk will experience a torque: Equation 1. We will solve for the moment of inertia I by using Equation 1. and ...

In applying Newton’s Second Law of Motion to rotational motion, it is known that the relation between torque and angular acceleration depends on both the mass and the distribution of that mass; this relationship is known as the moment of inertia. The moment of inertia for discrete distributions of mass is …

Chris’ rad bicycle wheel has a radius of 38 cm and is given an angular acceleration of 2.67 rad/s2 by applying a force of 0.35 N on the edge of the wheel. What is the wheel’s moment of inertia? A toy top has a rod with a diameter of 8.0 mm and a disk of mass 0.0125 kg and diameter of 3.5 cm. The moment of inertia of the rod can be neglected.

In the second method, the moment of inertia is determined experimentally by measuring the acceleration produced by a constant torque on the body. The experimental determination of the moment of inertia is only valid if friction is negligible. In Part II of the experiment, an estimate of the angular acceleration due to friction is obtained.
