Gear cogs made from ferrous metals need to have teeth which are resistant to frictional wear, while the centres which are attached to the shaft need to resist the torques applied to the cog.
A Watch
There is a picture of a gear in the related link. a gear tooth is one of the things on the outside of the gear that sticks out. This gear has 18 teeth.
Reverse gear
Attached to a gear are many tires. The tires are used the land the aeroplane. That is why it is called landing gear.
A number of gears grouped into a single unit is called 'gear train'.If two gear's in mesh eg, a drive gear and a driven gear also constitute a gear train which are called simple gear train and in the simplest form.simple gear train may have more than two gear's.compound,epicyclic,reverted are some other types of gear train's.
Gear Cogs all move at the same speed, at the same time, just for moving one cog.

* If it is stiff and making a crunching noise when going into gear it means the syncromesh (which is the cogs between gear cogs are worn), If it is making a whining noise in first gear it's a flywheel in the clutch, if it makes a whistling noise while travelling the clutch needs replacing, failing all that the gearbox needs grease or your elbow does.
A series of teeth around the outside of a wheel ... looking just like a gear wheel.
A pinion gear is turned along a rack of cogs, moving it either way.
The rear cogs on a bike are part of the gear system that helps the rider adjust the resistance and speed of pedaling. The purpose of the rear cogs is to provide different gear ratios, allowing the rider to pedal more easily uphill or go faster on flat terrain. By changing the rear cog, the rider can adjust the bike's performance to suit different riding conditions.
There are several different types of switchgear power systems and each have their own unique characteristics to meet the specific needs of the system and its location. A very effective form of switchgear power systems is a gas insulated switchgear (GIS) system. In this type of system, conductors and contacts are insulated by pressurized sulfur hexafluoride gas. While effective, it is very expensive, however. Other common switchgear power systems include oil insulated and vacuum switchgear. A circuit breaker is also an important part of switchgear power systems and their safety and function. A circuit breaker that is housed within switchgear power systems enclosures is a primary component that can interrupt fault currents. A circuit's arc is quelled when the circuit breaker pulls apart the contacts and disconnects the circuit. The design of this system requires careful consideration regarding how and where it will be utilized. Generally speaking, circuit breakers fall into four major categories; oil, gas, vacuum and air.

Put simply... it's a circle of links that connects the drive gear (attached to the pedals) to the speed gear(s) - attached to the rear wheel. Rotating the drive gear (using the pedals) transfers the movement to the gear cogs on the rear wheel - which propels the bicycle forwards.
The rear cogs on a bicycle are part of the gear system that helps the rider adjust the resistance and speed of pedaling. The purpose of the rear cogs is to provide different gear ratios, allowing the rider to pedal more efficiently based on the terrain or desired speed. By changing the rear cog size, the rider can make it easier or harder to pedal, affecting the bike's performance in terms of speed, power, and efficiency.
