  1. CHAPTER 5/6 TEST OUTLINE

  2. Spaghetti Bridges: • Know “Span”, “Compression”, and “Tension”

  3. Sec. 5.4 Pressure • Define • Units • Formula • Calculations • Affect of increasing/decreasing force on pressure • Affect of increasing/decreasing area on pressure

  4. Atmospheric Pressure • Define • Things affecting atm. P • What happens to atm. P as you increase/decrease in elevation • Explain why there is a change to atm. P at different elevations with respect to gravity and # of molecules

  5. 5.5 Pneumatic vs. Hydraulic Systems • Advantages of fluid-powered systems • Examples of hydraulic systems • Examples of pneumatic systems • Advantages and disadvantages of hydraulic systems • Advantages and disadvantages of pneumatic systems • Parts found in each systems

  6. Pressure and Forces in Hydraulic Systems • Gain in force = lost in distance • Larger cylinder will have larger force but will move less in distance • Smaller cylinder will have smaller force but will move more • Proportional to size difference squared

  7. KMT and pressure • Spacing between molecules of gas vs. liquid • Compressibility of gases vs. liquids • Explain delay in pneumatic systems w.r.t. molecules • Explain affect on volume

  8. 6.3 Hydraulics • Parts of the system • Comparing human heart to car fuel pump

  9. 6.4 Pneumatics • Parts of the system • Comparing human lungs to car fuel pump

  10. GAS LAWS • Boyle’s Law ( P =  V and vice versa) • Charles’ Law ( T =  V and vice versa) • Lussac’s Law ( T =  P and vice versa) • Explain these laws in terms of KMT (what is happening at the molecular level?)

  11. REMEMBER: • Study all NOTES, CYU questions, worksheets and vocabulary • HW: Study guide which includes vocabulary for Ch.5 (p. 164) and 6 (p. 180) **omit the words “ballast” and “exotic species”
