Experiment 9: Maxwell’s Wheel Introduction: The second lab performed on 2/1/12 involved two investigations concerning Maxwell’s wheel. Maxwell’s wheel is an apparatus that consists of a large disk with a long axle. The disk then bound to a support hanging from above with strings attached to each end of the axle. Maxwell’s wheel is considered to be an important apparatus to investigate physical phenomenon’s because it its ability to combine straight line motion and rotation of a rigid body

M is the mass of the car‚ g is equal to the acceleration due to gravity (9.8m/s2) ‚ µ is the coefficient of sliding friction between sand and tires (0.5 at most)‚ and a is the acceleration of the car. Solving for a we get: a = µg = (0.5)(9.8m/s2) = 4.9 m/s2If we assume a relatively constant acceleration

machines was recently proposed. Ball mill A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rotating cylinder is partially filled with balls‚ usually stone or metal‚ which grinds material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%. Ball mills are characterized by their smaller (comparatively) diameter and longer length‚ and often have a length 1.5 to 2.5 times the diameter

1. Determine the spring constant‚ k‚ of Spring 1‚ by using Hooke’s Law. Take three different measurements (since 3 masses) and do three calculations and average your k’s to get a more accurate answer. By applying lots of friction‚ you will be able to get your mass to hang still. Show a table of your data and your calculations of k. Spring 1 with three different masses: 50 grams: Spring stretched: 5m F = 50gm * 9.8 m/s2 = 490.00 N K= 490/5m = 98 100 grams: Spring stretched: 10m F = 100gm * 9

However Aristotle failed to further test his hypothesis in order to take into consideration other variables such as air resistance‚ surface area and friction. Galileo conducted many experiments to prove his theory correct that objects of different masses‚ dropped from the same height will reach the ground at the same time. (Kallos‚ 2004) Galileo also deduced that in a vacuum‚ all objects fall at the
