-Last Lab
-Frame: Continued sandblasting the key parts of the frame
-Fasteners: Taught how to drill and thread
-Bottom End: Continued Disassembly
-Clutch: Took apart rotor and continued disassembly
-Top End: Sandblasted the head and cleaned other parts
-Calculating Overall Gear Ratios:
-Bottom, Second, Third, Top
-Engine Top Speed: 6000 RPM
-Ratio: Rear Wheel Speed vs. RPM
-Ex. Rear Wheel Speed = RPM/ Overall Gear Ratio
-Rotor connected to gear clutch basket with chain
-Rotor rotates -> Rotates the Gear a certain fraction -> Rotates the Drive Chain Gear -> Drives the rear sprocket a certain fraction
-Real Example: Tiger Gear Ratios
-Gearbox: 17 and 54 (tooth)
-Drive Chain Gear: 17
-Rear Sprocket Gear: 54
-Engine: 19 Teeth
-Clutch Basket: 48 Teeth
-Use information to find max speed of the motorcycle (roughly 60 MPH)
-Main Shaft and Layshaft
-Main: Goes through engine body
-Clutch Basket is Connected to Main Shaft
-Sprocket attached to output gear
-Friction
-F= (coefficient of Friction) x (N: Normal Force)
-Coefficient for Asphalt = 1.0
-Force= Weight of Bike + Weight of the Rider/ 2 (wheels)
-Downward Force = 200 Pounds x 1 = 200 pounds of shear force
-F= MA
-A= 1/2G (Due to 2 Wheels): Find length to get to 60 MPH
-Torque= Length x Force
-200 Ft*lbs till engine slips -> Divide by Gear Ratio = Torque of Rotor
-Tension in Chain = Torque of Rotor/ Radius of Rotor
-Gear Box Ratio:
-Drive Chain Sprocket Gear Relative to Gear Clutch Basket Rotation

-Left Exhaust Pip Blue Coloring: Engine is Running Hot; Chrome turns blue when hot
-Metal Gas Tank -> Engine Making Sounds
-Engine Being Warm -> Engine Pinging: Air is heated and explodes on its own due to compression: No need of spark plug
-Chain Lubricant: Yield and Motor Oil: Penetrating oil for rust and dirt: Motor Oil: Doesn’t evaporate
-Piston, Wheels, and Gears: Moving in Coordination with each other
-System of parts connected
-Key Ideas:
-Phaedrus: Electric Shock Therapy -> New Personality
-Has Never Met Phaedrus: Phaedrus was very unique, intellegent
-Handful of Sand: Knife Cutting through the façade of reality
Chapter 8
-Motorcycle References
-Adjusting the Engine: Tuning the engine to get into specs
-Lose Tappet: Need the engine to be cold due to the hot metal expanding
-Specs set when the engine is cold
-Porcelain in Plug:
-To much gas, not enough air:
-Color of Spark Plug Indicates if the combo is lean, rich, or optimal
Key Ideas
-Individuals in a System are not responsible for the outcome or status quo
-Patterns and Underlying Culture determine structures and systems
-Systemic Problems arise from the underlying culture
