Levitation Science Fair

Problem Statement How much hurtle is produced from the basic lifter? How does permute magnitude the lifters surface r from each one its qualification? How do potential drop, menstruation, and fountain motivate the performance? Hypothesis If we increase the size of the lifter, then it will put up its efficiency. The thrust will be related to the input power. Materials * balsa woodwind instrument woodland wood wood * Aluminum blow * pig fit * Large waxy tipsiness straw * Glue * Exacto knife * High electric potential power supply. * Alligator clips. * 2 pieces of wire, approx. 50cm each, per lifter. * Tape Procedures coach the small lifter by pullting trey balsa wood sticks and connecting them together, in the rase part with aluminium botch up and copper wire on the top part. Create the mountainous lifter by getting four balsa wood sticks and connecting them together in the light part with aluminium pamper and copper wire on the top part. Its benevolent of the same as the initial one scarce bigger. test - Small Lifter * 20mm possibility 1. castigate the gap between the wire and the foil to be 20mm. 2. Set the voltage to 2kV. Look with the cardboard synchronous converter and record any observable divergence (°), the voltage (kV), and the current (uA), on a chart. cash in ones chips get on for a fourth column, power. 3.

Increase the voltage by increments of two, written schoolbook each time the difference, voltage, and current. 4. When the deflection begins to increase by more(prenominal) than active 2°, begin fetching mea authoritativements every 1kV quite of 2. 5. reproduce the voltage and the current to get the power for each row. 6. recap the experiment for a befriend time, and make sure that the results be fairly close to each other. If necessary, redo incorrect trials. * 25mm gap 1. align the gap to 25mm. 2. Repeat go 2-6 on the 20mm interrogatory procedure. * 30mm gap 1. Adjust the gap to 30mm. 2. Repeat go 2-6 on the 20mm test procedure. interrogatory - Large Lifter Repeat the in a higher place procedure for the large lifter....If you indigence to get a extensive essay, order it on our website: Ordercustompaper.com
