Week 10 April 13th Scribe Notes

Updates:

  • Bill Becker’s presentation has been moved to April 20th
  • We will continue reading one chapter of Shop Class as Soulcraft per class for the rest of the semester

Shop Class as Soulcraft Chapter 3 Discussion:

  • Discussion leader: Taylor- accessibility for fixing stuff independently; dependence on others vs self
  • Hien – Motorcycle reference: kicker starter on early motorcycles
      • Prof Littman:  easier to start m/c when its on center stand b/c it is more stable; it’s important to listen to the exhaust/intake in order to get it at the right point in the cycle to get the m/c started
  • Hien – M/C reference: oil pump-old m/c used a hand pump rather than an automatic pump
      • Prof Littman: oil pump was mounted on the handle bars; manual lever for retarding spark; retard fully when starting the m/c otherwise the engine could run in reverse, then once the m/c is started advance the spark; amount of advance affects the power
  • Rupert – society removed option to fix things, ex) Mercedes removing dipstick; made a connection to class where we machine our own parts rather than buying them when we have the need
  • Anna- discussion of music and freedom; idea founded on obedience to instrument
      • Prof Littman: agency vs autonomy; agency = skilled on instrument, the thing; autonomy = playing radio, the application
  • Anna – Greek philosophy; different levels of knowing
  • Cecilia – user of technology is passive; people have to disengage with it sometimes otherwise it becomes frustrating
  • Hien – easier & more intuitive = more assessable for larger audience vs keeping it specific and customizable
  • Taylor – discussion of learning curves &  automatic vs manual
  • Adam – pg. 68-69 what separates humans from other animals; “handiness”

Fusion 360:

  • Went over how everyone is progressing with Fusion 360
  • Computer Aided Engineering Analysis in Fusion360
      • Create object
      • go to Simulation
      • click Static Stress Analysis
      • loads-> cases-> constraints->select a face (anchors surface)->ok
      • loads->select face & set magnitude->ok
      • results->solve->results->animate-> check two way & set steps

Circuit Simulator:

  • http://falstad.com/circuit/circuitjs.html
  • simulated ignition system (see photo library)
