1. Give one other example of each of the types of systems.
Examples of
Mechanical System-Ski and Poles
Optical Energy- Solar cells used in Garden Light bulbs
Hydraulic System-Work Lifts
Electric System- Washing machine and Dryer
2. Choose a natural system and a human made-system. For each one, identify the subsystems, components, mechanisms, inputs and outputs.
3. Most systems have side effects that aren’t part of their output. Name some side effects associated with the transportation system.

2. Choose a natural system and a human made-system. For each one, identify the subsystems, components, mechanisms, inputs and outputs.
Mechanical System
Nature made
Bones and Muscles: Built-in Levers
Every time you move a finger, arm, or toe, you are using a lever. Your bones act as levers and each of your joints acts as a fulcrum. Tendons attach muscles to your bones.
Human made
Brakes-A brake is a mechanical device that inhibits motion by absorbing energy from a moving system
Optical System
Nature made
Plants use sun to make chlorophyll using photosynthesis involve plant cells
Human made
Solar Power Bulb-which convert solar radiation directly into electricity using photovoltaic cells
Hydraulic System
Nature made
The human cardiovascular system, as well as the circulatory systems of many other organisms, are also good examples of hydraulic systems. In this type of natural hydraulic system, the heart serves as a central pump, which sends out oxygen to the body using a pressurized fluid, blood.
Human made
Hydraulic Jack-their use of an incompressible liquid, such as hydraulic fluid or jack oil, as the means by which force multiplication is achieved.
Electrical system
Nature made
Lightning. Lightning and thunder happen simultaneously, but lightning travels near the speed of light while thunder moves at the speed of sound, approximately 866,000 times slower than the speed of light, which explains the delay between the two phenomena
Human made
Television- consists of many different forms of components such as motors, resistors, capacitors, and transistors. These components are designed to be connected in an electrical circuit.
3. Most systems have side effects that aren’t part of their output. Name some side effects associated with the transportation system.
The environmental impact of transport is significant because transport is a major user of energy, and burns most of the world's petroleum. This creates air pollution, including nitrous oxides and particulates, and is a significant contributor to global warming through emission of carbon dioxide.
