Experimental procedure and Data Collecon: 1. Setup the distance between the pulley and the oscillator to 1m. Use a meter stick to take this measurement and discuss HOW your group determined the end point for the pulley node. Make sure to detail HOW your group determined the end points of this measured distance L in your group repolt. For the first part of the experiment, hand a mass of arm g on the string. 2. Connect the two wires [black and red} from the Pasoo oscillator to Clutput 1 in the S50 Interface. 3. Open Capstone. Click on Signal Generator. Click on 85:] Output 1. The waveform should he set to \"Sine\". Stalt at a frequency of 25 Hz and increase it in increments of 1-1o Hz looking for the resonant frequencies on the string that has 4 antinodes. 4. Once the string is close to resonance [you observe a stable standing wave}, change the stepping increment to 0.1 Hz and ne-tune your resonant frequency. You may need to go back and forth a few times to determine the frequency at which the LARGEST displacement occurs- -that is your resonant frequency for the 4 antinode oscillation, i.e. n = 4. Record this resonant frequencies and number of antinodes in a table in Excel. 5. Examine how the frequency affects the # of antinodes. Keeping the length and the mass constant, change the frequency required to produce antinodes n=1, 2, 3, 5, I5, 3!, and 8. Record these frequencies and annodes in Excel. 6. Now, return the oscillator to the frequency found in Step 4 [for 4 antinodes] to examine how the tension affects the number of antinodes. Keeping the frequency and the length constant, change the mass [and therefore Tension]I on the sting until you nd as many standing waves as possible between 0.05 kg oo kg. Note that your group should be able to nd 5 data points. Analysis: 1. Create graphs of the antinode vs. frequency and antinode vs. tension in Excel. 2. Using the trendline feature in Excel, choose the appropriate fit for the two plots and fit your group's data. Make sure the fit equations show on the two graphs. 3. Predict the value of the constant. 4. Now, for all linear data - compare the slope value from Excel to the constant value shown in the theory section. How does your data compare to the predicted constant value calculated? Discuss. 5. If the data is not linear - compare the calculated constant value for the proper equation shown on page 5 to the fit constant from the Excel trendline feature. How does your data compare to the predicted constant value calculated? Discuss. 6. The value of u is only known to 2.5% precision. Is this uncertainty sufficient to state that your Excel fit constants equal the calculated constant value for these experiments? Explain. 7. Discuss in your group the impact of the pulley friction. How does your group predict this friction, if present, would impact data results? Explain reasoning. 8. Discuss the stretchy string - if the u changes during the experiment with changing masses would its value tend to increase or decrease? Explain.
