Introduction
In this experiment, we will use Maxwell’s Wheel, two sets of brass knobs, two standing
support rods, Vernier Caliper, string, stop watch, and a scale.
In investigation one, we
will first measure the dimensions of the disk and axle, too find their volumes.
Then we
will find the mass of the disk and axle together by using a scale.
By using the volumes
we calculated we can now find the mass of each axle and disk.
Finally we will calculate
the moments of inertia for the disk and the axle, to find the total moment of inertia for the
entire Maxwell’s Wheel.
In investigation two, we will study the downward motion of the
wheel.
We will trying to find the acceleration and the moments of inertia.
First though
we need to the find the heights of wheel when wound eight, six and four times.
This can
be found using the equation 2*pi*radius of axle*num of times the string is wound.
We
will do four trials at each height, by winding the string the given amount of times and
releasing it from that height, to find the time it takes the wheel to become fully unwound.
From these trials we can then find the average time and average time squared.
We will
then also calculated the errors of each of these.
Once the errors are found we will graph
the height vs the time squared.
This is the end of the preview.
