PROCEDURE:
Setup:
Mount the Rotary Motion Sensor on the rod stand (see Figure 3).
Attach the Angle Indicator as in figure 3.
Put the pulley on the Rotary Motion Sensor with the largest step outward. Attach the rod to the Rotary Motion Sensor pulley and put the two 75 g masses on the end of the rod.
Plug the Rotary Motion Sensor into a PasPort input on the 850 Universal Interface.
Adjust the Adjustable Angle Clamp for an initial angle of 0.
With the pendulum at rest, click open Hardware Setup at the left of the screen. In the bottom right of the Hardware Setup panel, click the Gear icon. De-select Zero Sensor Measurement at Start by clicking on the checkmark. Click on the Remove Sensor Zero Offset button. Then click on the Zero Sensor Now button. Click OK. Click Hardware Setup to close the panel.
Procedure:
Displace the pendulum from equilibrium (no more than 10 degrees [0.17 rad] amplitude) and let go. Click RECORD. Let the timer run for 20 seconds and click STOP. Read the period on the digits display and record it in your notes.
The oscillations should be symmetric about 0 degrees, but the period will not be affected if they are not symmetric. If they are not symmetric, you can fix it by repeating step 7 of Setup.
Increase the angle by 5 degrees and repeat. Continue until the final angle is 850. Note: if you have set up the Adjustable Angle Clamp as shown in Figure 3, then you must rotate the pulley under the Rotary Motion Sensor for the jam nut on the clamp to work correctly. See figure 4. If you have trouble getting the desired angle and your angle is slightly off, just make sure to use the actual value in your analysis (and change the value in the angle column of your table if previewing your data in Capstone).
Remove one of the brass masses and repeat the entire experiment (note: you will need to find the effective length again, but this time it is only necessary to do one trial at each angle).
