Notes and tests:

1. Level with bubble level, using bottom wire support block as leveling point.
2. Pulley should be mounted on the side without the PASCO logo.
3. Mount the disk on top of the pulley with the screw presently holding the pulley.
4. If string needs attaching to more pulleys follow the instructions from lab 9 . Wrap the string around the largest pulley so that it comes out from the back side which results in the pulley spinning clockwise when the string is pulled.
5. Do initial setup with thinnest wire: tighten bottom wire support on wire first, then tighten top wire support on wire, then move RMS down until it sits just in the top wire support so that the wire is straight but firm, and not falling off.
6. Start the test file “2305 Lab 10 test.cap” in the Test files. Hook the force probe to the string, start collection, and gently pull away from the setup with the string coming from around back.
   When tested there should be a positive linear slope on the angular position vs. applied force graph.
