Main Purposes Is To Increasing Speed Using Mechanical Gear Increase The Force On The Wheels The Pedals Car Make: Make Le's Efforts Sustainable

Gears are mechanical components that transmit rotation and power from one shaft to another if each shaft has correctly formed projections (teeth) evenly spaced around its circumference, such that as one shaft rotates, the next tooth enters the space between the teeth of the other shaft. Gears are systems that transmit rotary motion from one shaft to another by meshing teeth together. Two significant characteristics of gears are the radius and the number of teeth. A shaft or base is usually used to mount or link them to other parts. Gears are teethed wheels that fit together. When one gear rotates, the other rotates as well. When the gears are of varying sizes, they can be employed to boost the turning force's power. The smaller wheel spins faster but with less force, whilst the larger one spins slower but with greater force. A gear is a simple spinning machine with teeth on one side (cogs). They transmit torque, which is similar to a twisting force, when they link to another gear.
