1. Set up the lab station as shown in the diagram below. pivot force probe string loop 2. Slide the loop of string along the meter stick to the 90 centimeter mark. Then move the force probe along the horizontal bar so that the string is hanging vertically, perpendicular to the meter stick. Lift the meter stick until the string goes slack, then zero the force probe. After the force probe reading goes to zero, lower the meter stick back to its original position. The force probe will now be measuring the tension in the string supporting the meter stick. Record this force in Table 1 below. 2. Slide the loop of string along the meter stick to the 90 centimeter mark. Then move the force probe along the horizontal bar so that the string is hanging vertically, perpendicular to the meter stick. Lift the meter stick until the string goes slack, then zero the force probe. After the force probe reading goes to zero, lower the meter stick back to its original position. The force probe will now be measuring the tension in the string supporting the meter stick. Record this force in Table 1 below. Table 1. Changing the Distance With 0 = 90 string position (cm) F(N) r (m) T (Nm) 90.0 0.842 0.74938 0.89 80.0 0.79 0.74655 0.945 70.0 1.082 0.69 0.74658 60.0 1.272 0.59 0.74048 50.0 1.525 0.74725 0.49 40.0 0.39 1.917 0.74763 0.29 30.0 2.581 0.74849 0.873758 20.0 0.19 3.882 3. Repeat step 2 for the string at the 80 cm, 70 cm, 60 cm, 50 cm, 40 cm, 30 cm, and 20 cm mark on the meter stick. 4. There is a hole in the meter stick that serves as the pivot point for this experiment. Measure and record the position of the hole below. pivot position = 1.0 cm 5. Slide the string to the 50 cm mark, and remove the pivot screw from the meter stick. Adjust the position of the string until the meter stick is perfectly balanced. This is the position of the center of mass of the meter stick. Record this position below. center of mass position = 50.0 cm 6. Hold up the meter stick until the string goes slack, then zero the force probe. After the force probe reading goes to zero, lower the meter stick back to its original position. The force probe will now be measuring the weight of the meter stick. Record the weight below. weight of meter stick = 1.517 N 1.
