    Development of Pneumatic Systems. (Check the boxes that apply)The solution to a control problem is worked out according to a system with documentation playing an important role in communicating the final result. The circuit should be drawn using standard symbols and labelling. Comprehensive documentation is required including most of the following: 
    • A. 

      Function Diagram

    • B. 

      Circuit Diagram

    • C. 

      Description of the operation of the system

    • D. 

      Technical data on the components

  • 6. 
    A pneumatic system is a system that uses compressed air to transmit and control energy.Pneumatic systems are used in controlling train doors, automatic production lines, mechanical clamps, etc
    • A. 

      True

    • B. 

      False

  • 7. 
    The designs of pneumatic components are relatively simple. They are thus more suitable for use in simple automatic control systems.
    • A. 

      True

    • B. 

      False

  • 8. 
    The pressure and the volume of air can't easily be adjusted by a pressure regulator.
    • A. 

      True

    • B. 

      False

  • 9. 
    Please select the advantages of the pneumatic systems:
    • A. 

      Low Effectiveness, Simple Design, Economical

    • B. 

      Easy selection of speed and pressure , Relatively low accuracy, Low loading

    • C. 

      Simple Design, Environmental friendly, Easy selection of speed and pressure

    • D. 

      Easy selection of speed and pressure, Low Loading, Noise

  • 10. 
    Charles's law (also known as the law of volumes) is based on:
    • A. 

      The absolute pressure of a confined gas is inversely proportional to its volume.

    • B. 

      The volume of a given quantity of gas varies directly with its temperature. The law only applies if the pressure to which the gas is exposed remains constant.

    • C. 

      The volume of a given quantity of gas varies directly with its temperature. The law only applies if the temperature to which the gas is exposed remains constant.

    • D. 

      The pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature.
