Remote lifting
Team up with another group so that you can monitor two Genecons on one handheld computer.
Connect the VoltageCurrent probe to your handheld computer. Refer to Technical Hints to connect the VoltageCurrent probe.
Connect the VoltageCurrent probe leads to the Genecon leads as shown in the diagram.
Start the software to read energy. Use one Genecon to drive the other, or each try to oppose the other. Stop recording. Look at the energy graph.
Sketch your graph. How did the graph relate to what you were doing with the Genecons? What are the energy transformations happening here?
Now attach a pulley to one of the Genecons. Leave the wires hooked up. Remove one handle. The pulley comes with a piece of plastic tubing (bushing). Fit the tubing on the Genecon shaft and slide the pulley tightly over the shaft.
Cut about 2m of thread or string. Tie one end through the hole in the side of the pulley.
Wind up the string onto the pulley. Attach a hanging weight. You can use a 50g mass from your kit or a heavier one of your own. A paper clip works as a hook. It has a mass of about 0.3g.
Hold the Genecon with its shaft horizontal and the string hanging down from the pulley. Its leads should still be hooked to the other Genecon, with the Voltage/Current leads in place.
Restart the software to read energy.
Crank the other Genecon to lift the weight. Also try to lower the weight. If the weight is heavy enough, will it fall by itself? Try different things, like raising and lowering slowly and quickly.
Save your data to your handheld computer. Sketch the graph and record the order in which you did things. Use Notes on your handheld computer.
