Necessary Mechanics - Brake
Desired Motion

• Brake pedal rotates about Brake Axis
• Normal motion of the brake is to depress it with
  a Downward Force
• This Downward Force transmits an Upward Force
  about the hinge of the pedal to the Brake
  Activation Bar
• Brake is activated by pulling up on this Brake
  Activation Bar

Brake Axis

Necessary Mechanics - Gas

• Gas pedal requires no mechanical advantage due
  to the very small amount of force necessary to
  depress it
• Consequently, entire motion of the gas is
  completed through cables, pulling down the gas
  pedal from behind

Description of Motion - Brake

• Motion begins with applied User Force
• User Force rotates Throttle Control about Axis 1
• Throttle Control slides down Brake Lever,
  applying additional Downward Force
• Brake Lever rotates about Axis 2, transmitting
  Downward Force into Upward Force
• Upward Force lifts brake control
