Automobiles and bicycles Water faucets, forklifts and cranes, and even toilet flush mechanisms These are all "complicated machines" created by combining combinations of six simple machines.
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.
Multiple compound machines are far more sophisticated than simple machines and are made up of many basic machines. Washing machines and automobiles are two examples. They are both composed of many parts that work together to accomplish a task.
Washing machines are complex machines because they include motors, electronic controls, and other components in their structure to perform their function. Automobiles are complex machines because they need special tools to repair certain parts of the vehicle. They also require regular maintenance to keep them running properly.
Simple machines are ones that can be operated by one person. They include engines and motors as well as other devices such as levers or wheels. These types of machines do not include sensors or electronic controls so they are easy to use but they can only perform one action at a time. For example, a motorized wheeled dolly can move something large but cannot cut materials or wash clothes at the same time.
Multiple compound machines are those that can perform several tasks simultaneously. For example, a dishwasher can wash dishes while you cook dinner at the same time. Complex machines may have several different parts to them; for example, a car has an engine, transmission, steering wheel, brakes, and door handles. Simple machines usually consist of one piece of equipment that performs multiple functions depending on how it is constructed.
A lever, pulley, wedge, screw, or inclined plane are examples of devices that act in a fundamental way in any machine. A device composed of two or more basic machines that operate in tandem. A screw is an example of a simple machine. A fastening device made of metal or plastic with a helical thread cut into one face used to attach things together. Also called threaded pin.
Screws can be divided into two general types: axial-threaded and cross-threaded. An axial-threaded screw has its threads running parallel to the axis of the screw. These screws are held in place by friction against some form of housing. An example of an axial-threaded screw is a wood screw. A cross-threaded screw has its threads at right angles to the axis of the screw. Cross-threaded screws are held in place by friction alone; they do not have any special design for engaging with a mating thread. An example of a cross-threaded screw is a sheet-metal screw.
Both axial-threaded and cross-threaded screws can be divided into three main categories according to the method used to create their threads: manual, electric, and automatic. Manual screws require strong hands and a high degree of skill to use properly. They are available in a wide variety of sizes and shapes. The driver used to drill the threads on a manual screw is known as a bit.

| A bathtub is this type of simple machine | inclined plane |
| stairs are this type of simple machine | inclined plane |
| A ladder leaned against a building is this type of simple machine | inclined plane |
| A bathroom sink faucet is this type of simple machine | wheel & axle |
There are a variety of basic machines in the bathroom. Levers, pulleys, and inclined planes are all examples of mechanical devices. The bathtub is one example. It is an inclined plane that directs the water to the drain. A faucet located at the end of the tub allows you to control the flow of water.
The toilet is another example of a mechanical device. It consists of an air-tight tank attached to a base with legs. You flush the toilet by pressing on a handle or button which opens a valve allowing water to fill the tank. When you release the button or handle, it closes this valve and stops the flow of water. The weight of this water raises the lid on the tank, which lifts the seat to create a void below it. This prevents any more water from entering the bowl when the tank is full.
Bathtubs and toilets work on similar principles: An object is used to open and close a valve so that water can be directed toward one side or the other. From there, it will continue to flow until something stops it.
These are just two examples of many simple machines found in the bathroom. Simple machines are easy to build and fun to experiment with. There are many different ways to use simple machines in your own bathroom design.
A water pump is made up of multiple tiny elements that work together to form a functional mechanism. The hub/pulley, bearing, body/house, seal, and impeller are the most basic components. They can be found in almost any water pump. The exception is electric pumps, which do not have an impeller.
The hub/pulley structure provides a solid foundation for the pump to stand on. It also creates an opening through which water can flow. This is known as the "inlet" side of the pump. The outlet side is where water leaves the pump and flows into your hose or pipe. Some pumps have two hubs/pulleys: one at each end. These allow the pump to function even when one side is clogged with debris.
Bearing housings hold the bearings that connect the shaft to the hub/pulley. They are usually made of steel or plastic. If you look inside a working pump, you should see three bearings: one inside each housing. These allow the shaft to turn but protect it from being damaged by objects in the water.
The body/house keeps water out while allowing the shaft to rotate.
