Those are gears, mechanical components that transmit motion between axles. Gears can vary in size and shape to control speed, torque, and direction in machines and systems.
Yes. And on those axles are where the wheels are situated.
Yes A Bicycle uses Wheels and the Axles Hold The Wheels Up Plus Some Bikes Have Levers
The three different subsystems are -frames and materials -gears and drivers -wheels and axles

Use a cotton swab dipped in kerosene. Gently wipe the gears with the swab. Force the gears to rotate by turning the wheels. Watch that you do not get the cotton caught in the gears. If you cannot or do not want to get kerosene, use fingernail polish remover that does NOT contain acetone.
Trains move by using electric or diesel engines to power the wheels through a system of gears and axles. The engines provide the necessary force to propel the train forward by turning the wheels, which grip the tracks and create movement.
You replace the gears in the axles.
Wheels, being round, help us to move things that are too heavy to drag along the ground. The axles are what hold the wheels together.
what the hell are you talking about the wheels are turned by the drive axles....stupidity
the axles. dombos@#$$%#
Frictional forces between the tires and the road surface provide the necessary traction for a bike to move forward. Additionally, friction between the bike chain and gears allows the pedaling motion to transfer power from the rider to the wheels, propelling the bike forward.
