Document Summary

Inertia is a concept relating to newtons laws. Inertia is resistance to the state of movement. Difficult to get something moving or getting it to stop. Moment of inertia is different: relates to how hard it is to get something to move or stop but its related to an object spinning about an axis and you can assign a number to it. One is a concept and one you can define by an equation and putting numbers to it. Moment of inertia relates to angular acceleration. Amount of torque in a system is proportional too inertia, moment of inertia, or acceleration. Angular acceleration with increase if amount of torque applied to system will increase as well. If you increase moment of inertia, will decrease angular acceleration- angular acceleration more difficult to chive if moment of inertia goes up. How difficult to spin something around an axis related to: Cog would be where mass would lie.

A stiff uniform wire of mass, Mo, and length, Lo, is cut, bent, andthe parts soldered together so that it forms a circular wheelhaving four identical spokes coming out from the center. None ofthe wire is wasted, and you can neglect the mass of thesolder.

What is the moment of inertia of this wheel about an axle throughits center perpendicular to the plane of the wheel?

If the wheel is given an initial spin with angular velocity, wo,and stops uniformly in time,T, what is the frictional torque at itsaxle?

A small piece of cheese is at the center of a disk of radiusRrotating about its axis. A hungry mouse is sitting at the edgeofthe disk. It will be able to eat the cheese when it is a distancer= R/4 from the center of the disk. The surface of thedisk,however, is slippery ...
In the following, assume that the disk is spinning freely aboutitsaxis and that there is no net external torque acting onthesystem.
a) Write expressions for the moment of inertia of the system(diskplus mouse) when the mouse is at the edge (distanceR) andwhen the mouse is at the distance r fromthe center. Themoment of inertia of the disk is I=(1/2)MR2.
b) As the mouse approaches the center, does the disk speed up,slowdown, or maintain its angular velocity?
c) Assuming the angular velocity is wwhen the mouse is at the edgeof the disk, find an expression forthe angular velocitywr whenthe mouse is a distance r = R/4from thecenter.
d) Evaluate the angular velocity wr for the case thatthe mass of thedisk is M = 18 g, the mass of the mouse ism = 16g, and w = 4 s-1. Answer:wr =10 s-1.
e) Determine if a static friction coefficient of ms =0.7 is sufficient to prevent themouse from slipping at r =R//4 for R =0.4 m. Please use g = 10m/s2.

A student sits on a rotating stool holding two 3.0 kg objects.When his arms are extended horizontally, the objects are 1.0 m fromthe axis of rotation, and he rotates with an angular speed of 0.75rad/s. The moment of inertia of the student plus stool is 3.0 kg·m2and is assumed to be constant. The student then pulls the objectshorizontally to 0.20 m from the rotation axis.

(a) Find the new angular speed of the student.
_______ rad/s

(b) Find the kinetic energy of the student system before and afterthe objects are pulled in.
before _______ J
after _______ J


I am really having trouble with the setup of this problem andhaven't been able to calculate the right answer. I need helpfiguring out how I should approach this. It would really help tosee the problem worked out to have something to compare my workwith so I can see where I'm making my mistakes. Thank you!
