Additional Instructions for setting up the Heat Engine Lab:

1. Slide the 90 cm rod throught the rod clamp of the Heat Engine and then into the "A" base. Tighten the rod in the "A" base and then tighten the Heat engine to the rod a few inch about the top of the "A" base.
2. Slide the RMS on to the 90 cm rod and tighten it about 1/3 length down from the top. The RMS pulley should be on the right side. The pulley should be mounted on the "Pasco Rotary Motion Sensor" label side of the RMS.
3. Attach to the 45 cm rod the three 90 degree clamps. One on each end and on approximatly in the middle. Refer to the picture to the right to see how the clamps are place. Attach the far left 90 degree clamp to the 90 cm rod about 8-10 inches above the Heat Engine rod clamp.
4. Insert the two temperture sensors into the middle and right 90 degree clamps and gentaly tighten them in. They should not be over tightened since the screw is just pressing against soft rubber.
5. Position the steam generator and large styrofoam cups underneath the temperature sensors. Lower the 45 cm rod down so that the temperature sensor are inserted about 2/3 of the way into the steam generator and the syrofoam cup. Tighten the left clamp to the 90 cm rod.
6. The string that is attached to the top of the Heat Engine platform should be strung up over the RMS pulley from the back to the front. Hang the 5 gram mass hanger from the loop in the end of the string. This maintains tension in the string so it stays on the pulley.
7. Attach all of the cables to the Pasco 750 interface as discribed above.

Procedure of removing #8 stoppers that have become stuck in the aluminum can:

1. Stuck stopper can often be removed by using the compressed air. There is an air valve in the tool box that can be attached to the compressed air supply in CHEMP 109.
2. The air valve has a nozzle that is removed and replaced with a threaded nipple. The threaded nipple has a piece of hose with a barbed connector on it.
3. The barbed connector is inserted into the hole in the stopper and a quick blast of compressed air will usually push the stuck stopper. Sometime refitting the hosing and giving it a second blast is required. So far this has always worked on at least the second try.
