A uniform disk with mass M and radius R is rotating about an axis through its center-of-mass. The axis is perpendicular to the disk. The moment of inertial for the disk with a central axis is I MR2. Two non-rotating smaller disks, each with mass M2 and radius R/4, are glued on the original disk as shown in the figure. (a) Show that the ratio of the moments of inertia is given by I'/I = 35/16, where I' is the moment...

The moment of inertia of a disk rotating about its axis of symmetry is Icm=1/2MR^2 The formula for finding the moment of inertia of an object rotating off axis if its on axis center of mass moment of inertia is I=Icm + Md^2 Given a disk 10cm in diameter whose mass is 1500g, find its off-axis moment of inertia if the disk is located 10cm from the axis rotation.
Problem 3: A merry-go-round can be considered a uniform disk of mass 145 kg and radius 2.10 m free to rotate about a frictionless axis through its center. A 40.0 kg child stands at the edge and the system is initially rotating at 0.300 rad/sec.

What is the angular velocity of the merry-go-round...
8. Th e moment of inertia for a wagon wheel can be calculated by taking the sum of the moment of inertia for a hoop (radius 1.2 m) rotating about a Cylinder axis (mass 3 kg) and three rods of length 1.2 m, rotating about their center perpendicular to their length, each of mass o.8 kg. If the wheel is rotating at an angular speed of 2.5 rad/s, what is the wagon wheel's kinetic energy as it spins in place?...
