Last Time:\u00a0<\/u><\/strong><\/p>\n

What did we do in Shop?<\/strong><\/p>\n

Wheels: used yield to loosen screws, break up rust, removed wheels<\/p>\n

Fork: removed and disassembled fork, discovered that fork is used for suspension and that there\u2019s a spring on the inside of fork, unique to this tiger cub because it has internal and external spring. Kept track of ball bearings<\/p>\n

Noted serial numbers to show that frame number and engine number match, shows that it\u2019s original<\/p>\n

Top end\u2014took engine off frame, started disassembly<\/p>\n

Frame\u2014took off rear suspension<\/p>\n

Bottom end\u2014took off oil lines, engine from frame<\/p>\n

Clutch\u2014working on casing of clutch side of engine Interesting technique: threaded rod at both ends, loosed nut and shaft stayed in engine block, needed to remove it so we used jam nut to lock two nuts to threaded shaft, and then used wrench to unscrew from the base<\/p>\n

\u00a0<\/em><\/p>\n

Note\u2014we\u2019re not certain that the way we take it apart is the way it\u2019s supposed to be! Have to use manuals and common sense, because people have taken this apart before<\/em><\/p>\n

Important Info on Blackboard<\/strong><\/p>\n

Tiger Cub Bible<\/em>\u2013intro, history, general information on tiger cub, gives diagrams of different systems within motorcycle and gives evolution of those systems (We have a T20SC)<\/p>\n

Troubleshooting guide<\/em>\u2013when things aren\u2019t working, good reference<\/p>\n

Workshop Manual<\/em>\u00a0\u2013 tells you how to disassemble and reassemble parts,\u00a0 targeted at our motorcycle<\/p>\n

 <\/p>\n

Important Info on our own Site<\/strong><\/p>\n

Shop Manual<\/em>\u2013Triumph\u2019s manual, how to take it apart and specifications of motorcycle<\/p>\n

Online Guide<\/em>\u00a0\u2013 tells you how to listen to engine to diagnose problem<\/p>\n

 <\/p>\n

If you were talking about how a motorcycle worked to a five year old, what would you talk about?<\/p>\n

Explosion of gasoline (C8H18) in the presence of air (O2), produces carbon dioxide, water vapor, and heat, which raises temp to about 2000 degrees kelvin, pressure increases a factor of 7, pressure pushes piston, that\u2019s why CO2 and water vapor come out exhaust<\/p>\n

Motorcycle references<\/u><\/p>\n

Tachometer\u2014measures engine speed, our motorcycle has a max of 6000 revolutions per minute<\/p>\n

Speedometer\u2014measures how fast motorcycle is going<\/p>\n

Resistance\u2014reduce frontal area and resistance by dropping head,\u00a0 important because we\u2019ll need to pay attention to drag and wind resistance<\/p>\n

 <\/p>\n

Storyline<\/u><\/p>\n

Phaedrus is his prior self, had been to this place where the narrator is, but narrator doesn\u2019t remember\u2014slows down because it\u2019s a familiar sight, d\u00e9j\u00e0 vu, goes into discussion about ghosts<\/p>\n

Says he doesn\u2019t know any ghost stories, but he does about Phaedrus (didn\u2019t want to tell his son). Not real, due to science, but they\u2019re real because they\u2019re real in people\u2019s minds.<\/p>\n

Are things real if people haven\u2019t thought of them yet? Gravity didn\u2019t exist until Newton came up with it. It\u2019s only there once we think of it.<\/p>\n

Our class said: just because someone hasn\u2019t defined it yet doesn\u2019t mean it doesn\u2019t exist, equating law of gravity to a material thing, strange argument<\/p>\n

Professor \u00a0 Littman\u2014gravity is a human creation of a concept, and the law of gravity we have right now could be different 100 years from now. Basically, we\u2019re not sure that gravity exists as we conceive it!<\/p>\n

 <\/p>\n

Storyline<\/u><\/p>\n

Set off again, very early, very cold<\/p>\n

Taking pictures, saving memories\u2014he doesn\u2019t want to take pictures, you would need a 360 lens to really take it in, just wants to live in the moment instead of trying to keep it<\/p>\n

Loving something is often a function of spending more time with it (like his gloves)<\/p>\n
