What's the difference between pedal and rudder?

Pedal


Definition:

  • (a.) Of or pertaining to the foot, or to feet, literally or figuratively; specifically (Zool.), pertaining to the foot of a mollusk; as, the pedal ganglion.
  • (a.) Of or pertaining to a pedal; having pedals.
  • (a.) A lever or key acted on by the foot, as in the pianoforte to raise the dampers, or in the organ to open and close certain pipes; a treadle, as in a lathe or a bicycle.
  • (a.) A pedal curve or surface.

Rudder


Definition:

  • (n.) A riddle or sieve.
  • (n.) The mechanical appliance by means of which a vessel is guided or steered when in motion. It is a broad and flat blade made of wood or iron, with a long shank, and is fastened in an upright position, usually by one edge, to the sternpost of the vessel in such a way that it can be turned from side to side in the water by means of a tiller, wheel, or other attachment.
  • (n.) Fig.: That which resembles a rudder as a guide or governor; that which guides or governs the course.
