Four - year - old
synchronizers performed more
like 5 - year - olds on these tests, while their nonsynchronizer counterparts performed more
like 3 - year - olds, Kraus says, and the
synchronizers were better at discriminating melodies and rhythms in music.
The
synchronizers have a wear material on them and can be shaped
like a cone and once the speeds of the shafts match (through the gear ratio), then the output shaft is connected to the gear and everything is spinning and power can be applied by releasing the clutch pedal.
