What is a gear or cogwheel -
ANSWER :
A rotating machine part with teeth or cogs, which mesh with another toothed part to trans-
mit torque
What is torque -
ANSWER :
The ability of a force to cause rotation around an axis.
What are two or more gears working in a sequence called -
ANSWER :
A train or a gear train
What can a gear train be considered and why -
