Calculate the moment of inertia of a ring of mass 4.1 kg, inner radius 7 cm, and outer radius 12 cm, about the axis passing through its center of mass and parallel to the axis of symmetry. Give your answer in kg.m2.
Problem 6. Find the moment of inertia of a solid torus of mass M, inner radius r, and outer radius R about
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 ring of radius 0.6 m has a mass of 5.0 kg, giving it a moment of inertia of 1.8 kgm2. If the uncertainty in the radius is 0.14 and that of the mass is 0.1, what is the uncertainty of the moment of inertia, in kgm2?
QUESTION 1 In procedure 2, trial 1, suppose you measure the ring to have mass 261.6 g, inner diameter 4.7 cm and outer diameter 6.39 cm. Calculate the moment of inertia of the ring to three significant figures in units of kg·m².
A compound disk of outside diameter 140 cm is made up of a uniform solid disk of radius 45.0 cmand area density 4.60 g/cm2 surrounded by a concentric ring of inner radius 45.0 cm , outer radius 70.0 cm , and area density 2.70 g/cm2 . Find the moment of inertia of this object about an axis perpendicular to the plane of the object and passing through its center.
(a) You are given a solid sphere of 20 kg and radius 40 cm. What is the moment of inertia along any tangent? (b) You are given a meter stick (mass is distributed uniformly) whose mass is 400 g What is its moment of inertia about the 60 cm mark? 4.
In procedure 2, trial 1, suppose you measure the ring to have mass 319.8 g, inner diameter 3.61 cm and outer diameter 8.27 cm. Calculate the moment of inertia of the ring to three significant figures in units of kg·m².
