MEMO To: Dylan Smith From: Cindy Nguyen Section: 907 Date: 09/12/16 Re: Lab 1 Fundamentals Part 1 Purpose: The purpose of this lab is to review and understand the basic mechanics concepts such as force, work, power, and efficiency, through simple experiments. Procedure: A student is first weighted and placed on a Colson Hoist. Students then measure the time, height and revolutions necessary to lift someone a certain distance. This data is then used to calculate circumference, work, efficiency, power and mechanical advantage. After drawing free body diagrams of the inclined plane students proceeded to place nuts and bolts in a cup to determine how much weight would be necessary to move the block from rest from those two angles (0, 30). The weight was recorded and used to find the static friction of the block against the surface. The final exercise was determining the speed, gear and torque rations of a gear given two gears, one being a driver and the other being driven. The gears were measured using a ruler, and this information was used to determine the circumference of the gears.
