Information about Wheel And Axle
The wheel and axle is a simple machine. It consists of a wheel that turns an axle, or an axle that turns a wheel. It is also a lever that turns in circles around a point or fulcrum. The load on the axle is more easily moved because of mechanical advantage. The wheel and axle can be considered to be a lever in which the radius of the wheel is the effort arm and the radius of the axle represents the resistance arm. It also is a single forced machine. By changing the short distance of lifting, the force is less because the work always stays the same.
One of the most common wheel and axles is the wheel of a car or truck. On most of these, the wheel and axle acts as a lever rotating around the fulcrum or the center point. On doing this the wheel rolls.
Screwdrivers, doorknobs, windmills, gears, and Chain Falls are all examples of the wheel and axle.

. simple machine is any device that only requires the application of a single force to work. Work is done when a force is applied and results in movement over a set distance. The work done is the product of the force and the distance.

wheel is a circular device capable of rotating on its axis, facilitating movement or transportation or performing labour in machines. A wheel together with an axle overcomes friction by facilitating motion by rolling. Common examples are found in transport applications.

axle is a central shaft for a rotating wheel or gear. In some cases the axle may be fixed in position with a bearing or bushing sitting inside the hole in the wheel or gear to allow the wheel or gear to rotate around the axle.

windmill is a machine designed to convert the energy of the wind into more useful forms using rotating blades. The term also refers to the structure it is commonly built on. In much of Europe, windmills served to grind grain, later applications include pumping water.

A gear is a component within a transmission device that transmits rotational force to another gear or device. A gear is different from a pulley in that a gear is a round wheel which has linkages ("teeth" or "cogs") that mesh with other gear teeth, allowing force to be fully
