1) Description of ratchet Gear
A ratchet gear is a specialized gear type that may only turn in one direction. Most ratchet gears have teeth
that are round on one side and flat on the other. The section of the ratchet that interacts with the gear,
called a pawl, will slide over the rounded side, but will get caught on the flat side. This one-directional spin
makes ratchet gears well-suited for tasks that require discrete points, such as clicks on a dial. Unlike many
one-directional gear systems, ratchets do allow a small amount of backward motion; this makes them better
for non-powered applications where slippage won’t cause damage.
