The most noteworthy of them are known as the "six basic machines": the wheel and axle, the lever, the inclined plane, the pulley, the screw, and the wedge, but the last three are simply extensions or combinations of the first three. The wedge is so called because it gives a wedging action. The lever is used for transferring forces from one point to another with little or no loss of energy. The pulley is like a small lever that can be used for lifting weights or materials. The screw is a fastening device in which a headless pin or screw goes through two objects and comes out the other side. Finally, the wedge is a tool used for shaping soft materials such as clay or wood.
These six machines are all that's needed to perform many useful tasks. A hammer, an axe, and a saw are examples of tools used in conjunction with these machines. In fact, almost any tool you might use at home or work can be classified as a form of machinery. For example, a food processor is actually a combination screw/wedge machine that uses a spinning metal blade to chop, mix, and grind ingredients.
Even vehicles such as cars and trucks are forms of machinery. They consist of multiple parts working together using different methods to produce a result: the mixing of oil and water to create an engine, for example.
The lever, wheel and axle, inclined plane, wedge, pulley, and screw are the six basic simple machines. Several of these small devices are interconnected. These connections allow one machine to provide an advantage for another; for example, by using a lever to lift something heavy or push against a wall.
For example, let's say you want to lift a book off the ground. You could use a lever arm to create more force, but that would be hard to do with just your body. Instead, you could use a screw drive to replace your hand. A person could then use their body weight to turn the screwdriver, which would in turn lift the book off the floor.
This shows that simple machines can be used to assist people who cannot use their own muscles. For example, a person who is sick or injured might need help lifting things they could not move alone. One person could use a tool such as a lever, wheel, or screw to aid the weak member of the pair.
In addition to assisting people who are unable to work themselves, simple machines can also be used as tools for working on projects at home or in the garage.
The inclined plane, lever, wedge, wheel and axle, pulley, and screw are examples of basic machines. More complex machines are built from these elements.
In mechanical engineering, a machine is an apparatus that changes energy contained in its input materials (most commonly wind or water) into other forms of energy such as motion, heat, or electricity. Machines can be divided into three main groups based on how they function: driving machines, power machines, and reducers. Driving machines include motors and engines, which produce rotary motion or oscillating motion directly from electrical input to facilitate movement of another object. Power machines convert energy from one form to another without producing motion itself, but instead uses motion produced by a driving machine to do work. Examples include dynamos and turbines. Reducers reduce the size of objects through cutting or crushing, or increase the size of objects by extruding material. They include presses, molding devices, and shredders.

There are five additional basic machines besides the wheel and axle. The inclined plane, the lever, the screw, the wedge, and the pulley are all examples. Simple machines are frequently combined to form compound machines. Compound machinery include automobiles, dishwashers, and lawn mowers. These are some examples of complex machines.
One of the six basic machines is a pulley. Other basic machines include the wheel and axle, inclined plane, wedge, screw, and lever. A pulley is a device used to transfer power or motion from a driving force such as a motor or engine to an output force such as a belt that can drive another motor or pump. Pulleys are used in many applications including hoists, air compressors, and industrial robots.
Pulleys consist of an inner ring and an outer ring that are joined by two or more cords or belts. The portion of the belt that runs between the rings forms the sheave. The diameter of the sheave determines how much friction it will produce when the belt passes over it. Most commonly, the sheaves are flat but other shapes are available. For example, some pulleys have cylindrical sheaves while others have octagonal sheaves. The choice of sheave shape and size can affect what kind of load the pulley can handle and how much power can be transmitted through it.
As you can see, pulleys are very useful devices that can make heavy loads seem like they are no burden at all for the driver. They can also increase the speed at which a motor can turn, which is why they are included in most motors today.
Simple devices such as the lever, pulley, inclined plane, screw, and wheel and axle are examples of machines. They are known as basic machines, and more complex machines are just combinations of them. The common hydraulic press is an example of a multi-stage machine because its action depends on how you set it up with additional components.
The pneumatic tire was invented by Charles Goodyear in 1823. The electric light bulb was invented by Thomas Edison in 1879. The phonograph was invented by Elisha Gray in 1877. And the radio was invented by Nikola Tesla in 1876.

Here is a list of some commonplace instances of basic machines.
The wheel and axle (pulley), an inclined plane, a screw, a wedge, and a lever are all examples of simple machines that are commonly used. While basic machines can amplify or diminish the forces that can be applied to them, they have no effect on the overall amount of effort required to complete the activity. For example, a lever can increase the force acting on its end away from the fulcrum by about its weight, but it requires as much energy to rotate the lever as it does to lift its other end.
The word "simple" is used here to describe how many parts there are to a machine. A complex machine will have several different types of motors or actuators used together to perform a single task. A simple machine uses one type of motor/driver to do everything. There are many simple machines available today, such as electric drills, circular saws, and even kitchen appliances such as blenders and food processors.
Some people think that any device that can be used for a purpose is a simple machine. This is not true. Some examples of simple machines include a crane, which is used for lifting objects, and a windmill, which is used for grinding corn or pumping water. These devices can be used for many other tasks as well, but they are always being reused as a form of mechanical advantage. In other words, they are tools that can help reduce the effort needed to complete a job.
