To come up with four examples of physical systems designed by people, we can start by understanding what a physical system is. A physical system refers to a collection of components designed to work together to achieve a specific purpose or function. These systems are often created by people to solve various problems or improve our quality of life. Here are four examples:

1. Transportation Systems: These include any system designed for the movement of people or goods from one place to another. Examples can range from simple systems like bicycles, cars, trains, and planes, to more complex ones like public transportation networks such as subways or highway systems.

2. Communication Systems: These are systems that allow the exchange of information between individuals or groups. Examples include telephones, mobile phones, the internet, radios, or television networks. These systems enable people to connect and share information over long distances.

3. Power Grid Systems: These are systems designed to generate, transmit, and distribute electrical power to communities and industries. Examples include power plants, electrical grids, transformers, and distribution networks. These systems are critical for providing electricity to homes, businesses, and industries.

4. Water Supply and Sanitation Systems: These systems are designed to provide clean water for consumption and remove wastewater for treatment. Examples include water treatment plants, pumps, pipelines, storage tanks, and sewage systems. These systems help ensure access to safe drinking water and maintain sanitation standards in communities.

To generate more examples, you can think about systems in other fields like healthcare systems, manufacturing systems, environmental systems, or even natural systems that have been modified by humans.
