• What is a mechanism designed to do?

  Make work easier to do
• How does a mechanism help in applying force?

  It allows a small force to apply a larger force
• What has made logging less labor-intensive?

  • Wheel & axle
  • Gears
  • Cams and followers
  • Levers
  • Belts and Pulleys
  • Shafts
• What are the three requirements of a control system?

  Input, Process, and Output
• What do mechanical control systems use mechanisms for?

  To control INPUT, PROCESS, and OUTPUT movement
• What is the term for the advantage gained from using mechanisms?

  Mechanical Advantage
• What mechanism is used to lift a car?

  Car jack
• How can systems be divided for better understanding?

  • Systems can be split into subsystems
  • Example: A bicycle as a system
  • INPUT: Movement of legs
  • PROCESS: Pedals and chain turning
  • OUTPUT: Bicycle moving forward
• What are the components of a control system's Input, Process, and Output?

  • INPUT: Rotating car jack handle
