2 Abstract The purpose of this laboratory experiment is to introduce the concept of torque. We plan to achieve this goal by the use of a meter stick fulcrum, three clip mass hangers of various weights, two unknown masses, and other known various masses. With the use of this apparatus we will be able to accomplish our main goal, which is to identify the mass of the two known masses and the meter stick’s mass. In graphing the data collected we will be able to determine the experimental values of each unknown mass, by finding it’s slope. This experiment has helped me better understand torque and it’s many relations with distance, and gravity.

3 Data: In order to have accurate data we must weigh and keep track of the clip hangers used on the meter stick fulcrum. Data Table 1: Exercise 1 Unknown Masses m 1 = 131.6 g m 2 = 200.0 g Fixed Position Vector r 1 = 35 cm r 2 = 20 cm Through the use of the laboratory scale and fixed position vectors given in the lab manual, we are able to upon the above information. Y-VALUES X-VALUES Mass Added to hanger #2 (g) m 2 (included m h2 ) (g) r 3 (cm) 25 40.95 26.5 45 60.95 28.5 65 80.95 30.3 85 100.95 32.1 105 120.95 34.0 125 140.95 36.0 145 160.95 37.8 In order to find the m 2 values you have to add the mass added to hanger 2 and add the weight of the hanger. As for finding the r 3 values you have to subtract 50cm from the
