A thin light string is wrapped around a solid uniform disk of mass M and radius R, mounted as shown. The loose end of the string is attached to the axle of a solid uniform disc of mass m and the same radius r which is can roll down without slipping down an inclined plane that makes angle θ with the horizontal. Find the acceleration a of the rolling disc. Neglect friction in the axle of the pulley. a =...

Find the uncertainty in the moment of inertia. Moment of interia of a disk depends on mass and radius according to this function I(m,r) = 1/2 m r2. Your measured mass and radius have the following uncertainties delta m space equals space 0.43 kg and delta r space equals space 0.11 m. What is is the uncertainty in moment of interia, delta I , if the measured mass, m = 6.43 kg and the measured radius, r = 10.14 m?

Lab 8 Assignment: Moment of Inertia 1) Moment of Inertia for Different Systems The resistance to rotational motion change is more involved than for linear motion because it not only depends on what the mass is, but also on how that mass is distributed about the axis of rotation. The farther away from the axis the mass is distributed, the greater the moment of inertia. Using this simple definition, for each of the following pairs of objects, determine which of...

Page 2 Rotational Motion Questions The formula for the moment of inertia of our disk rotating about its center is I-(1/2)MR2. Calculate the moment of inertia for the three following combinations of 1. mass and radii: ) IfRi 0.150 m and M 4.450kg, then I =? ii) If R2 0.050 m and M2 20.000kg, then I =? iii) If Ry 2.500 m and M3 0.0080kg, then I3 = ? iv) In determining the moment of inertia of an object with...

A flywheel is a solid, rotating disk that is sometimes used to store energy. The moment of inertia for a solid disk is 1/2MR^2 where M is the mass and R is the radius. If a flywheel weighs 15kg and has a radius of 0.8m, determine the following. A) If a point on the outside of the disk is moving at 6 m/s, what is the angular velocity of the flywheel? B) If the flywheel starts from rest...

A soda bottle cap wobbles when spinning. Assume that the cap is a thin disk of radius R and a mass M attached to a cylinder of height R, radius R, and mass M, as illustrated below R-height-radius Derive the moment of inertia tensor I around the bottle cap's center of mass. As measured relative to its own center of mass, the MOI for a disk around the principal axis perpendicular to the plane of the disk (ê3) is 1/2MR2,...

2) Moment of Inertia for Multiple Objects We have loosely defined the moment of inertia as the difficulty or resistance encountered when trying to change an object's rotational motion. What if we were trying to rotation a combination of objects? a. Suppose you have a very light cloth pouch, and you place an apple of mass M=200 grams in it. You tighten up the satchel and start to swing it around, with the string in the satchel making a length...
