Thompson Date Chasity of Experiment: October 4, 2011 Report Submitted: October 4, 2011 Title: Simple Machine - Lever Purpose: The experiment was designed to calculate the efficiency of a machine by constructing first, second, and third class levers and testing different loads using a spring scale to measure force and the mechanical advantage of the levers. Procedure: We used a yard stick, metric ruler, 500 gram spring scale, pencil, quarters, paper cup, string, and different objects of different weight to measure the mechanical advantage of first, second, and third class levers. Data Tables: Data Table 1: Fulcrum at 15 cm Trial Trial 1 Trial 2 Trial 3 Trial 4 Load (Mass) 1 quarter 2 quarters 3 quarters 4 quarters Distance from Load from Fulcrum 19 cm 19 cm 19 cm 19 cm Effort (Mass) 1 quarter 1 quarter 1 quarter 1 quarter Distance of Effort from Fulcrum 10 cm 6 cm 3cm .05 cm Ratio: Effort Distance/Loa d Distance .52 .31 .15 .002 Data Table 2: First Class Lever, Fulcrum at .46 m Trial Trial 1 Trial 2 Trial 3 Trial 4 Load (Mass, N) 2.05 1.9 2.1 2.1 Load Distance, m .26 .26 .36 .41 Effort Force, N 1.66 1.61 1.91 2.11 Effort Distance, m .38 .38 .38 .38 M.A. 1.23 1.18 1.10 1.00 Data Table 3: Second-class Lever, Fulcrum at .91 m Trial Trial 1 Trial 2 Trial 3 Trial 4 Load (Mass, N) 2.1 2.1 2.1 2.1 Load Distance, m .1 .2 .3 .4 Effort Force, N 2.31 2.41 2.61 2.71 Effort Distance, m .85 .85 .85 .85 M.A. .90 .87 .80 .77 Data Table 4: Third-class Lever, Fulcrum at .91 m Trial Trial 1 Trial 2 Trial 3 Load (Mass, N) 2.1 2.1 2.1 Load Distance, m .9 .9 .9 Effort Force, N 2.01 4.61 3.76 Effort M.A. Distance, m 1.04 .23 .45 .46 .55 .70 Observations: If using the same weight with a second class lever the distance you moved from the fulcrum point is close to the amount of the effort force increase. Calculations: 1. In Experiment 1 calculate the ratios of the measured distances; i.e. the rations of Effort Distance/Load Distance. In the data table above 2. In Experiment 2, Part I, II, & III convert grams as needed to Newtons. In the data tables above 3. In Parts I, II, & III calculate M.A. for each trial of each lever type. In the data tables above Questions: A. In Experiment 1 you calculated the ratios of the measured distances, i.e. the ratios of Distance. Effort Distance/Load What is the significance of these ratios? How did your calculations compare to your expectations? It is significant because it is the theoretical determination of the ratio of how much the machine is helping you. I honestly did not have any expectations of what the calculations would be because I was unfamiliar with this type of project. B. The spring balance is reasonably accurate for determining the load mass. However, the spring balance weighs 62 grams. Explain how to use the Work(in)=Work(out) principle to verify the mass of the spring balance. In order to determine several parts of the equation needed for the Work-in=Work-out formula you would need to determine effort force which is multiplied by the effort distance to come up with the amount of Work-out. In order to do that you have to add the measured amount from the spring scale reading by the provided spring scale mass (62g or .61N) and by verifying the calculations of Work-in (Load mass multiplied by load distance) and Workout (Effort force multiplied by effort distance), you verify the spring scale balance. C. After examining the 1st class lever data what kind of general statement can be made with regards to mechanical advantage and the relationship of load distance to effort distance? The load distance and effort distances were similar in length from the fulcrum point. D. What happens to the mechanical advantage for 2 nd class levers as the load moves further away from the fulcrum? The mechanical advantage is decreased when the load moves further away from the fulcrum. E. What is the significance of the mechanical advantage of class 3 levers? The mechanical advantage decreases when the effort force is moved further away from the fulcrum point. F. What class lever is represented by a fishing pole? A fishing pole would be considered a third class lever. G. What kind of lever is represented by an oar used in rowing? Why? An oar would be considered a first class lever because the fulcrum point is in the middle of the oar and the force is being used by both ends of the oar. Conclusion: The experiment helped to understand many different things. I learned how to measure mechanical advantage and learn the importance of it as well as determining how to measure effort force.
