-Last Lab<\/strong><\/p>\n

-Frame: Continued sandblasting the key parts of the frame<\/p>\n

-Fasteners: Taught how to drill and thread<\/p>\n

-Bottom End: Continued Disassembly<\/p>\n

-Clutch: Took apart rotor and continued disassembly<\/p>\n

-Top End: Sandblasted the head and cleaned other parts<\/p>\n

-Calculating Overall Gear Ratios:<\/strong><\/p>\n

-Bottom, Second, Third, Top<\/p>\n

-Engine Top Speed: 6000 RPM<\/p>\n

-Ratio: Rear Wheel Speed vs. RPM<\/p>\n

-Ex. Rear Wheel Speed = RPM\/ Overall Gear Ratio<\/p>\n

-Rotor connected to gear clutch basket with chain<\/p>\n

-Rotor rotates -> Rotates the Gear a certain fraction -> Rotates the Drive Chain Gear -> \u00a0\u00a0Drives the rear sprocket a certain fraction<\/p>\n

-Real Example: Tiger Gear Ratios<\/p>\n

-Gearbox: \u00a017 and 54 (tooth)<\/p>\n

-Drive Chain Gear: 17<\/p>\n

-Rear Sprocket Gear: 54<\/p>\n

-Engine: 19 Teeth<\/p>\n

-Clutch Basket: 48 Teeth<\/p>\n

-Use information to find max speed of the motorcycle (roughly 60 MPH)<\/p>\n

 <\/p>\n

-Main Shaft and Layshaft<\/p>\n

-Main: Goes through engine body<\/p>\n

 <\/p>\n

-Clutch Basket is Connected to Main Shaft<\/p>\n

-Sprocket attached to output gear<\/p>\n

 <\/p>\n

-Friction<\/p>\n

-F= (coefficient of Friction) x (N: Normal Force)<\/p>\n

-Coefficient for Asphalt = 1.0<\/p>\n

-Force= Weight of Bike + Weight of the Rider\/ 2 (wheels)<\/p>\n

-Downward Force = 200 Pounds x 1 = 200 pounds of shear force<\/p>\n

-F= MA<\/p>\n

-A= 1\/2G (Due to 2 Wheels): Find length to get to 60 MPH<\/p>\n

-Torque= Length x Force<\/p>\n

-200 Ft*lbs till engine slips -> Divide by Gear Ratio = Torque of Rotor<\/p>\n

-Tension in Chain = Torque of Rotor\/ Radius of Rotor<\/p>\n

 <\/p>\n

-Gear Box Ratio:<\/p>\n

-Drive Chain Sprocket Gear Relative to Gear Clutch Basket Rotation<\/p>\n

-Left Exhaust Pip Blue Coloring: Engine is Running Hot; Chrome turns blue when hot<\/p>\n

-Metal Gas Tank -> Engine Making Sounds<\/p>\n

-Engine Being Warm -> Engine Pinging: Air is heated and explodes on its own due to compression: No need of spark plug<\/p>\n

-Chain Lubricant: Yield and Motor Oil: Penetrating oil for rust and dirt: Motor Oil: Doesn\u2019t evaporate<\/p>\n

-Piston, Wheels, and Gears: Moving in Coordination with each other<\/p>\n

-System of parts connected<\/p>\n

-Key Ideas:<\/p>\n

-Phaedrus: Electric Shock Therapy -> New Personality<\/p>\n

-Has Never Met Phaedrus: Phaedrus was very unique, intellegent<\/p>\n

-Handful of Sand: Knife Cutting through the fa\u00e7ade of reality<\/p>\n

Chapter 8<\/strong><\/p>\n

-Motorcycle References<\/p>\n

-Adjusting the Engine: Tuning the engine to get into specs<\/p>\n

-Lose Tappet: Need the engine to be cold due to the hot metal expanding<\/p>\n

-Specs set when the engine is cold<\/p>\n

-Porcelain in Plug:<\/p>\n

-To much gas, not enough air:<\/p>\n

-Color of Spark Plug Indicates if the combo is lean, rich, or optimal<\/p>\n

 <\/p>\n

Key Ideas<\/p>\n

-Individuals in a System are not responsible for the outcome or status quo<\/p>\n

-Patterns and Underlying Culture determine structures and systems<\/p>\n

-Systemic Problems arise from the underlying culture<\/p>\n","protected":false},"excerpt":{"rendered":"
