We have to re-seal the inner timing cover on the green motorcylcle. It is really important to make it totally clean before re-sealing.<\/p>\n<p>&nbsp;<\/p>\n<p>Daniel \u2013 One of the forks in the transmission has come apart so we have to re-assemble that<\/p>\n<p>&nbsp;<\/p>\n<p>Kate \u2013 We had a little play around watching the piston move up and down and then oiled the piston<\/p>\n<p>&nbsp;<\/p>\n<p>Reese \u2013 Used a strap wrench. There were threads inside a bush on the stanchion that were puzzling.<\/p>\n<p>&nbsp;<\/p>\n<p>Anna \u2013 Depending on where you put the key on the rotor, you change whether you\u2019re powering the motorcycle with a battery or energy transfer.<\/p>\n<p>&nbsp;<\/p>\n<p>\u201cA battery makes it easier to start the bike. The magnet is a six-pole magnet that creates a current. The trick is to fire when the current is greatest to get the biggest spark. If you miss the window where there is current, you won\u2019t get a spark. This highlights the importance of timing. FYI, doesn\u2019t matter whether you fire on positive or negative.\u201d M. Littman<\/p>\n<p>&nbsp;<\/p>\n<p>Benjamin \u2013 There was no ground-breaking news. Continuing to wire and solder with the aim of making the taillights work.<\/p>\n<p>&nbsp;<\/p>\n<p>Cecilia \u2013 Needed to sand blast a piece before welding because you need electrical contact. Started to dry sand a tank so that the primer would apply well.<\/p>\n<p>&nbsp;<\/p>\n<p>Macey \u2013 Saw an engine that Jon had milled for demonstration.<\/p>\n<p>&nbsp;<\/p>\n<p>Rupert \u2013 Had a look at the evolution of the shape on the barrel and cylinder over the years.<\/p>\n<p>&nbsp;<\/p>\n<p>Kaixing \u2013 Ordered a set of stanchions.<\/p>\n<p>&nbsp;<\/p>\n<p>Daphne \u2013 2 side taillights only have one wire coming out of it. Figured out that some of the lights ground themselves automatically.<\/p>\n<p>&nbsp;<\/p>\n<p>Hien \u2013 Starting to work towards the fender. Looking at cutting to shape and size and drilling holes into them.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>Prof. Littman\u2019s background is not in motorcycles, but in spectroscopy, or the behaviour of atoms when they are excited. He is, however, best known for his work in tunable lasers.<\/p>\n<p>&nbsp;<\/p>\n<p>Spark Demo: We saw an adaptation of how the ignition coil works in a motorcycle. There is no spark until you slide the outer coil over the inner coil.<\/p>\n<p>&nbsp;<\/p>\n<p>THE SPARK IS THE STRIPPING OF ELECTRONS AND INVOLVES HEATING UP THE METAL. IT IS THIS HEAT THAT IGNITES THE GASOLINE.<\/p>\n<p>&nbsp;<\/p>\n<p>Bud Light Demo: You can see what chemicals are present in a reaction based on the light that is produced. With this in mind, you can use fibre optics in an engine to see what\u2019s happening inside.<\/p>\n<p>&nbsp;<\/p>\n<p>Alternator Demo: The iron core is key to creating the voltage.<\/p>\n<p>&nbsp;<\/p>\n<p>Rupert Peacock<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Joseph Henry \u2013 first Secretary of the Smithsonian Institution.
