A crucial part of a piece of machinery starts as a flat uniform
cylindrical disk of radius R0 and mass M. It then
has a circular hole of radius R1 drilled into it, see the
figure.(Figure 1) The hole's center is a distance h from
the center of the disk.
1. Find the moment of inertia of this disk (with off-center
hole) when rotated about its center, C. [Hint: Consider a
solid disk and "subtract" the hole; use the parallel-axis...
A disk with uniform density and radius 0.596 m used to weigh 24.48 kg, but then a hole was punched out. The black arrow in the image above shows the axis of rotation. The hole has radius 0.0951 m, and has its center 0.164 m away from the center of the disk. What is the moment of inertia of the disk with a hole? (Hint: only a scientist could call a hole negative mass! Find the mass taken away based...
A flat, uniform disk of mass 0.400 kg has a radius of 0.130 m. It accelerates from an angular speed of 85 rad/s to 262 rad/s in 18.0 s . Calculate the Moment of Inertia . Calculate the applied torque.
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...
Constants Part A To get a flat, uniform cylindrical satellito spinning at the correct rate, engineers fire four tangential rockets as shown in the figure (Figure 1). Suppose that the sateilite has a mass of 1400 kg and a radius of 3.3 m,and that the rockets each add a mass of 250 kg. What is the steady force required of each rocket if the satellite is to reach 32 rpm in 2.5 min, starting from rest? Express your answer to...

6_1. A majorette in a parade is performing some acrobatic
twirlings of her baton. Assume that the baton is a uniform rod of
mass 0.120 kg and length 80.0 cm.
a. Initially, the baton is spinning about a line through its center
at angular velocity 3.00 rad/s. (Part A figure) What is its angular
momentum? Express your answer in kilogram meters squared per
second.

angular momentum to solve problems involving...
Consider the following mass distribution where the x- and y-coordinates are given in meters: 5.0 kg at (0.0, 0.0) m, 3.3 kg at (0.0, 3.5) m, and 4.0 kg at (2.9, 0.0) m. Where should a fourth object of 7.5 kg be placed so that the center of gravity of the four-object arrangement will be at (0.0, 0.0) m? A 1.25 kg solid, uniform disk rolls without slipping across a level surface, translating at 4.00 m/s. If the disk's radius...
