    When tourquing a bolt assembly, what is the force applied to overcome friction?

    • Torsion

    • Tension

    • Tensile

    • Shear

    Correct Answer
    A. Torsion
    Explanation
    When torquing a bolt assembly, the force applied to overcome friction is called torsion. Torsion refers to the twisting force that is applied to an object, in this case, the bolt, in order to tighten it. This force helps to overcome the resistance caused by friction between the bolt and the surfaces it is being tightened against.

    What do you use as junction points for circuits that are frequently disconnected?

    • Conneector plugs

    • Terminal boards

    • Shielded wires

    • Splices

    Correct Answer
    A. Conneector plugs
    Explanation
    Connector plugs are used as junction points for circuits that are frequently disconnected because they provide a secure and reliable connection that can be easily disconnected and reconnected as needed. They are designed to withstand repeated use and ensure a stable electrical connection, making them ideal for circuits that require frequent disconnection, such as in portable devices or equipment that needs to be frequently moved or reconfigured. Terminal boards, shielded wires, and splices may also be used in certain situations, but connector plugs are specifically designed for this purpose.

    (809) Which one of these is a disadvantage of a continuous-flow oxygen regulator?

    • It wastes oxygen.

    • It is unusable below 10,000 feet.

    • It is usable only above 20,000 feet.

    • It delivers oxygen at varying pressures.

    Correct Answer
    A. It wastes oxygen.
    Explanation
    A continuous-flow oxygen regulator is a device used to control the flow of oxygen from a tank to a patient. The disadvantage of this type of regulator is that it wastes oxygen. This means that some of the oxygen being delivered is not being effectively used by the patient and is instead being wasted. This can be a concern, especially if the oxygen supply is limited or if the patient requires a high flow rate of oxygen for an extended period of time.

    • Air.

    • Nitrogen.

    • Hydrogen.

    • Carbon dioxide.

    Correct Answer
    A. Nitrogen.
    Explanation
    The correct answer is nitrogen. Nitrogen is used in the inflation cylinder of a multiplace liferaft to ensure that it will inflate in extremely low temperatures. Nitrogen is an inert gas that does not react with other substances, making it a safe and reliable choice for this purpose. It is also less prone to freezing than other gases, making it suitable for use in cold environments.

    (803) In a liquid coolant system, what tells you that the liquid coolant filter is dirty?

    • The system shuts down.

    • A warning light flashes.

    • A warning horn alarm is activated.

    • A mechanical pop-up indicator is activated.

    Correct Answer
    A. A mechanical pop-up indicator is activated.
    Explanation
    A mechanical pop-up indicator is activated when the liquid coolant filter is dirty in a liquid coolant system. This indicator serves as a visual signal to alert the user that the filter needs to be cleaned or replaced. It is a simple and effective way to ensure that the coolant system is functioning properly and that the coolant is clean. The other options, such as the system shutting down, a warning light flashing, or a warning horn alarm being activated, may indicate other issues or malfunctions in the system, but they do not specifically indicate that the liquid coolant filter is dirty.
