Homework:
Quiz using Pressure Calculations
Workbooks from fluids unit (chapter 9) - due Wednesday (to be marked)
Workbooks pages 50 - 55
Textbook Activity 4.2 Frequency Formula calculation

Class Work:
Reviewed Pressure Calculations.  A quiz will be given on Pressure Calculations on Wednesday, October 29th.  Be sure and understand how to convert from mass (measured in kg) to force (measured in N).  Remember the units for pressure are (Pa), when force is in kg and area is in m 2 .

Discussed
  - Hydraulic systems (fluid transportation, hydraulic multiplication - lifting a car, problems with hydraulic systems)
  - Pneumatic systems (definition, problems with pneumatic systems)
