They can operate machines by rotating. The first gear cog rotates and mobes the next one around, which then moves then next one round. They can change the speed of things sometimes. They can also change some other things..
the purpose of a quick change gear box (as the name suggests) is to allow you to change gear quickly.
A bevel gear can change the direction of the driven shaft/axle by 90 degrees. If different tooth counts are used, bevel gears can also change the ratio between speed/strength of the turning motion.
The difference between highest peak and the lowest valley of error line drawn when the gear is rotated by one revolution by a master gear in tight mesh.
An idler gear supports a belt, routes a belt around obstructions, increases the amount of area a belt contacts a pulley, or adds tension to a belt or chain drive system. In the case of a gear chain, the idler would reverse the motion of the gear it drives.
yes it can
Gear Cogs all move at the same speed, at the same time, just for moving one cog.
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.
cogs
* 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 pinion gear is turned along a rack of cogs, moving it either way.
A series of teeth around the outside of a wheel ... looking just like a gear wheel.
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 cogs on the gear may be worn from abuse or just wear and tear. since first gear is used for pulling and other types of recreation you also may check the clutch plate in the tranny and clutch.
what are cogs made out of
Well your transmission has to be overhauled. The shifter fork moves up and down on the shift gear and in and out of the gear cogs to allow it to shift gears.
