1) Description of How gear shaft Work
A gear shaft is the axle of the gear, providing the rotation that allows one gear to engage with and turn another.
The process is often known as gear reduction and is essential to transferring horsepower from engine to
drive mechanism. The conversion of engine speed into torque is what provides the driving force powering,
for example, the wheels of an automobile. Through the gears and shafts in an automobile transmission,
the engine is able to run at a constant speed, while the auto wheels can be run faster or slower, or even
in reverse, using the same engine rotational direction and speed.
