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

Wheels: Took off exterior of the rim of the wheel<\/p>\n

Frame: Sandblasted the joints of the frame<\/p>\n

Bottom End: Continued Disassembling<\/p>\n

Clutch: Studied functions and assembly of a clutch on computer<\/p>\n

Fasteners: Used CAD system to model parts<\/p>\n

Top End: Continue cleaning parts; prepared head for sandblasting<\/p>\n

–Dynamometers<\/strong><\/p>\n

-No load speed: 1200 RPM<\/p>\n

-Pulley gets tightened and RPM slows down<\/p>\n

-Radius of Pulley: 1 Inch<\/p>\n

-Linear Relationship between friction force vs RPM (Negative Relationship)<\/p>\n

-Torque vs. Speed Curve<\/p>\n

-Peak of Power Curve = Half of Max RPM<\/p>\n

-Power is lost through heating up the string<\/p>\n

-String is applying friction to the rotating wheel<\/p>\n

 <\/p>\n

-Hill Curve<\/strong><\/p>\n

-Force vs. Velocity<\/p>\n

-Bicycle Example: Applies to Transmission<\/p>\n

-Optimal Velocity<\/p>\n

-Power Curve: Force x Velocity<\/p>\n

 <\/p>\n

-Brake Components<\/strong><\/p>\n

-Tightening Bolt: Puts friction on the rotating bar<\/p>\n

-It resists it tendency to turn<\/p>\n

-It slows down the rotating shaft<\/p>\n

-Power slowly decreases as force and velocity decrease causing the bike to stop<\/p>\n

 <\/p>\n

-Power up a hill<\/strong><\/p>\n

-Power= mgv<\/p>\n

-PE= mgh<\/p>\n

 <\/p>\n

–Grading for the Course<\/strong><\/p>\n

-Precept Participation<\/p>\n

-Commenting in Class<\/p>\n

-Adding to Discussion<\/p>\n

 <\/p>\n

-Shop Class: Master of what you do in shop<\/p>\n

-Function on your own<\/p>\n

-Develop of shop skills<\/p>\n

-Problem Solving Abilities in Shop<\/p>\n

 <\/p>\n

-Final Presentation: 60%<\/p>\n

 <\/p>\n

SCAS: Chapter 3<\/strong><\/p>\n

Motorcycle References:<\/strong><\/p>\n

-Valve Train: Chain, Sprocket, Cam:<\/p>\n

-Used with more than one piston<\/p>\n

-Controls which valve is in use<\/p>\n

-More compression<\/p>\n

-Alternative to push rod<\/p>\n

-Valve Covers: Simply put, a part of the engine that covers the valves<\/p>\n

-Kick Starter: Used as ignition system of motorcycle<\/p>\n

-Oil Hand Pump:<\/p>\n

-Manual Oil Distribution System<\/p>\n

-Cast Iron: Holds oil well<\/p>\n

-Intake Stroke: Stroke of the engine that brings air into the cylinder<\/p>\n

-Throttle: Device for controlling power to engine, thus speed<\/p>\n

-Choke: Controls the air flow into the carburetor, thus controlling the fuel to air ratio<\/p>\n

-Spark Timing:<\/p>\n

-Spark Advance<\/p>\n

-Faster the rotor spins: The more the spark would advance<\/p>\n

-If to fast: Can reverse the engine<\/p>\n

-Used to be manually adjusted<\/p>\n

-Determines when the spark is set<\/p>\n

-Foot Peg: Peg where rider puts feet while riding<\/p>\n

-Exhaust Stroke: Final stroke of an engine in which burned fuel (H20 + CO2) is released<\/p>\n

-Dipstick: Measure amount oil that\u2019s in the oil tank<\/p>\n

 <\/p>\n

SCAS Chapter 3 Discussion: (Key Points)<\/strong><\/p>\n

 <\/p>\n

-In effort to make people more independent from technology (automating processes) people become more dependent: Freedom from necessity of fixing and problem solving.<\/p>\n

 <\/p>\n

-Lack of Freedom<\/p>\n

-Inability to fix or understand the technology we have<\/p>\n

-We are dependent on others to fix technology for us<\/p>\n

-In an effort to make it more user friendly, we are no longer able to fix<\/p>\n

-Can\u2019t do anything if technology breaks down<\/p>\n

 <\/p>\n

-Two Types of viewing technology<\/p>\n

-Classical: Fix your own technology, you can control your technology<\/p>\n

-Romantically: Technology has control over you<\/p>\n

-Represent two different types of approaching technology<\/p>\n

-Everyone is a mix of both<\/p>\n

 <\/p>\n

-Desire for individuality<\/p>\n

-Customization of technology<\/p>\n

-People want to feel like they are part of the process<\/p>\n

-Enjoy the process more than the product<\/p>\n

-Takes away problem solving ability<\/p>\n

-Limited to predetermined process<\/p>\n
