  • Hydraulics
    • Liquids are virtually incompressible
      • Volume does not change when under pressure
    • Pressure in liquids are transmitted equally in all directions
    • Pressure is force per unit area
      • Pressure (N/m2) = Force (N) / Area (m2)
    • Hydraulic systems
      • Force multipliers
        • Use small force to produce bigger force
        • Larger area, larger force = force = pressure x area
      • Force applied to system - effort
      • Force exerted by system - load
      • Example: Hydraulic car jacks
        • Used to lift a car
          • Handle pressed down, oil forced out of narrow cyclinder into wider cylinder
            • Pressure of oil forces piston in wider cylinder outwards
              • Piston forces pivoted lever to raise car
