What is the bike and the axle?
The round and axle, acquired as a couple, forms the most important of all simple machines. The axle is a cylindrical rod and the wheel is a circular object in the shape of a disk with a hole in the center, which is the right size for axle acceptance. Most axles are designed to have a bike at both ends. The wheels turn around the axle that is connected to some type of vehicle. The invention of the bike is one of the most important in the history of a person that is similar to the discovery of fire and the development of writing and electricity.
The earliest display of vehicles with wheels dates back to approximately 3500 BCE. At about the same time, the wheels of wheels appeared in what is now Russia, Mesopotamia and Europe, so the exact location of its origin is not known. It is possible that the wheels and remedy were created before this, but there is no archaeological evidence to confirm or refute it.
This simple machine provides a huge mechanical advantage in the execution of moving objects from one place to another.By turning the axle, the wheel overcomes the friction that would be generated by dragging the load it carries. The mechanical advantage of the wheel is obtained by using some force on the bike around its axis. The earliest vehicles were cars and simple cars, pulled by humans, horses or other animals.
In modern times, it can find a bike and axle in dozens of applications with small efforts. This simple machine is used by cars, bikes and almost any other form of land transport. Even aircraft use bikes and axles for their landing equipment. Office chairs, wheels and skates use all variants of this device.
Over the centuries, from their invention, the bike and the axle have been adapted to many use with many improvements and adaptations. Common devices using Rope are rolling around a strong axle. Turning the wheel that was often equipped with handles located around the perimeter was obtainedCana of a great mechanical advantage that allowed to move or lift heavy loads. The gears associated with wheels and axles allow the power to multiply between the power source and the wheels. For example, a simple wheel can provide a mechanical advantage of the factor several times work that is applied to the pedals.
