Equipment List:

1. Pasco 750 Lab interface with the following sensors:
• Pasco Power Amplifier (Analog A)
2. Wave driver plugged into the power amplifier (C21.1)
3. Red (C21.H) and Black (C22.H) banana plug cord connecting the power amplifier and the wave driver
4. Vibrating cord (approximately 2.5 m long) (C21.2).
   Tie a loop in each of the ends.
5. Small universal clamp(C20.4), 15 cm rod with smart pulley (C10.2)
6. Large universal clamp(C20.4), 45 cm rod (A1), and right angle clamp (C10.3) to attach cord.
7. Hanging mass set (C10.1)
8. 50 gram mass holder (C10.2)
9. 2-meter stick (A1) with supports and 2-pointers (C21.2).

General class use (2 of each per quadrant):

1. Sample of vibrating cord less than 1m long (C21.2) to measure the cord’s linear density.
2. Electronic balance (1000 gram capacity) (A2.3).
3. Meter stick (A1).

Notes and tests:

1. Set the equipment back from the front edge of the table about half the width of the table, and bring the mouse and keyboard in front of the setup.
2. Set it up such that the wave driver is on the side of the table closest to the lab interface.
3. Place the pulley so it is about level with the knot tied at the other end.
4. Place one of the pointers past the support near the pulley. Place the other pointer between the two supports.
5. Load “2306lab01_test.ds”, click “on” on the oscillator control panel.
6. If the wave driver oscillates, then exit the program. If not, then check the wiring.
7. Make sure when the mass holder hangs over the pulley with no extra weight the knot is not on the pulley and when you add 300g to the mass holder is does not touch the floor (if only barely).
8. Ignore the red caution light. This is only caused by the amplitude being set over 3V, and we want it set to 5V.
9. Test Case: With a 150 g mass a frequency of about 10.6 Hz should create the second harmonic.
