  1. Fluid Power A WebQuest for Technology Education By: Connor Kelly

  2. What Is Fluid Power • Energy controlled by the use of pressurized fluid (liquid or gas). • This can relate to both hydraulics and pneumatics.

  3. Hydraulics • Uses pressurized liquid • Many types of liquid can be used • Hydraulics can be found in many places. • Use this website to find two types of liquid and 5 uses for hydraulics. • http://science.howstuffworks.com/transport/engines-equipment/hydraulic.htm

  4. Pneumatics • Uses compressed air or gas to transfer energy. • This also uses many types of gasses • There are also many uses of pneumatic technology. • Use this website below to find 2 types of gases and 4 uses of pneumatics http://www.eng.iastate.edu/twt/Courses/Undergrad/packet/info/pneumaticsinfo.htm

  5. How Does Fluid Power Work? • Pascal’s Law: • “Pressure exerted by a confined fluid acts undiminished equally in all directions” • Who is Pascal? Find 5 facts about him here: • http://oregonstate.edu/instruct/phl302/philosophers/pascal.html • In other words, no pressure is lost when transferring it through fluid power technologies.

  6. What Are Some Advantages? • Easy to control/Easy power transfer • Always a constant force • High amount of force for it’s low weight. • Quick response

  7. What are some Disadvantages? • Possible fire/explosive hazard for some liquids • Must not contain any outside debris • Difficult to clean up

  8. Find and explain how hydraulic pressure is used in everyday objects. • Use these websites: • http://www.ehow.com/about_5478901_uses-hydraulic-systems.html • http://www.tpub.com/content/engine/14037/css/14037_67.htm • http://www.hydraulicmania.com/hydraulic_lift.htm • http://www.allstar.fiu.edu/aero/hydraulics.htm
