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?
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.
Please help Points: 10 12) A 18 kg solid disk pulley of radius 0.11 m rotates about an axis through its center (a) What is its moment of inertia? (b) Starting from rest, a torque of 0.22 m-N will produce what angular acceleration? FIGURE 8-5 13) A solid disk with diameter 2.00 meters and mass 4.0 kg freely rotates about a vertical axis at 36.rpm. A 0.50 kg hunk of bubblegum is dropped onto the disk and sticks to the...
A thick ring has inner radius 1/2R, outer radius R, and mass M. Find an expression for its rotational inertia. Express your answer in terms of the variables R and M.
Each of the double pulleys shown has a centroidal mass moment of inertia of 0.25 kg-m2, an inner radius of 100 mm, and an outer radius of 150 mm. The mass m = 15.6 kg and the bearing friction is neglected.
Q3 - Determine the moment of inertia of the aluminum ring, Iring, shown in Figure 3 given the following parameters associated with the ring: mass M = 61 grams; and inner and outer radii, a = 6.35 cm and b = 7.6 cm, respectively. Q4 - A 108 gram Frisbee is 24 cm in diameter and has about half its mass spread uniformly in a disk, while the other half is concentrated in the rim of the Frisbee. With a...
Determine the moment of inertia of the half-ring of mass m about its diametral axis a-a and about axis b-b through the midpoint of the arc normal to the plane of the ring. The radius of the circular cross section is small compared with r. Use the values m = 7.0 kg and r = 300 mm. m Answers: laa kg.m2 Ibb = kg.m2
