Gear element=

All about engine;The gearbox is a rotating leVer.Different sizes of gear are applied to take mechanical advantage of these. If two same gear are rotated then Gets strength.But do not get mechanical strength.But if a small gear rotates a big gear Then Increased gear walking will decrease And doing this will provide mechanical advantage. Mean will make more power, And if you did revers it then. If the big gear rotates the small gear then the speed of the smaller gear will increase .In this way we can get strength and speed both from the gear box By doing this you can get straight and speed
