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. Using the slope from our graph we can then find the moment of inertia and acceleration for investigation two. In investigation three, we will add two knob weights to the wheel, so that the knobs are as far from each other as
