Questions and Answers
  • 1. 

    The lubricator in a pneumatic circuit is the ________.

    • A.

      First element in line

    • B.

      Second element in line.

    • C.

      Last element in line

    • D.

      Third element in line

    Correct Answer
    C. Last element in line
    Explanation
    The lubricator in a pneumatic circuit is typically placed as the last element in line. This is because the lubricator is responsible for adding lubrication to the compressed air before it enters the pneumatic components. Placing it last ensures that all the components in the circuit receive the lubrication they need for smooth operation.

  • 2. 

    Series circuits work on both hydraulic and pneumatic actuators.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Series circuits work on electrical circuits, not hydraulic or pneumatic actuators. In a series circuit, the components are connected in a single path, which means that the current flows through each component one after another. Hydraulic and pneumatic actuators, on the other hand, use fluid power to generate motion, not electrical current. Therefore, the statement that series circuits work on hydraulic and pneumatic actuators is false.

  • 3. 

    _____________________ is the use of liquids or gases under pressure to move objects or perform other tasks.

    • A.

      Water Power

    • B.

      Fluid power

    • C.

      Airpower

    • D.

      Turbine power

    Correct Answer
    B. Fluid power
    Explanation
    Fluid power refers to the use of liquids or gases under pressure to move objects or perform other tasks. This can include hydraulic systems that use liquids, such as oil, to transmit force, or pneumatic systems that use compressed air or gas to achieve the same purpose. The term "fluid power" encompasses both types of systems and highlights the importance of using fluids to generate and transmit power in various applications.

  • 4. 

    Comparing the operating cost of hydraulic systems to pneumatic systems generally, they are.

    • A.

      More expensive to operate..

    • B.

      Less expensive to operate

    • C.

      Cost about the same to operate

    • D.

      No answer

    Correct Answer
    B. Less expensive to operate
    Explanation
    Hydraulic systems are generally less expensive to operate compared to pneumatic systems. This is because hydraulic systems use fluids, which are more efficient in transmitting power and require less energy to operate. On the other hand, pneumatic systems use compressed air, which is less efficient and requires more energy to generate and maintain. Therefore, hydraulic systems have lower operating costs, making them a more cost-effective option in the long run.

    Infinitely variable directional control valves should be mounted as close as possible to the actuator. 

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Infinitely variable directional control valves should be mounted as close as possible to the actuator because it allows for more precise control of the actuator's movement. By minimizing the distance between the valve and actuator, there is less chance for pressure drops or fluctuations, resulting in smoother and more accurate operation. This also helps to reduce the risk of leakage or inefficiencies in the hydraulic system. Therefore, it is true that infinitely variable directional control valves should be mounted as close as possible to the actuator.

  • 6. 

    Refrigeration type air dryers remove water from an airline by chemical absorbent action. 

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Refrigeration type air dryers remove water from an airline by cooling the air to a temperature where the water vapor condenses into liquid form. This liquid is then separated from the air and drained out. Chemical absorbent action is not involved in this process. Therefore, the given statement is false.

    Rate this question:

  • 7. 

    Common filter locations are 

    • A.

      Suction line, cylinder line, and return line

    • B.

      Suction line, pressure line, and return line

    • C.

      Pressure line, return line, and pilot line

    • D.

      All of above

    Correct Answer
    B. Suction line, pressure line, and return line
    Explanation
    The correct answer is suction line, pressure line, and return line. These are the common filter locations in a system. The suction line filter is used to remove contaminants from the fluid before it enters the pump. The pressure line filter is placed after the pump to remove any remaining contaminants before the fluid is distributed to the system. The return line filter is located in the return line to filter the fluid before it returns to the reservoir. Having filters in these locations helps to ensure that the fluid circulating in the system is clean and free from contaminants.

    _____________ is a force on a unit surface area (such as a square inch).

    • A.

      Load

    • B.

      Area

    • C.

      Pressure

    • D.

      Newton

    Correct Answer
    C. Pressure
    Explanation
    Pressure is defined as the force exerted on a unit surface area. It is the amount of force applied per unit area, such as pounds per square inch (psi). Pressure can be calculated by dividing the force applied by the area over which it is distributed. In this context, pressure is the appropriate term to describe the force on a unit surface area.

    Pascal law/principle states that when a force is applied to a confined liquid, the resulting pressure is transmitted unchanged to all parts of the liquid.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Pascal's law or principle states that when a force is applied to a confined liquid, the pressure generated by the force is transmitted equally to all parts of the liquid. This means that the pressure is distributed uniformly throughout the liquid, regardless of its shape or size. Therefore, the statement "True" is correct as it accurately describes Pascal's law.

  • 10. 

    _________________ are fluid power systems based on the use of air or another gas.

    • A.

      Turbine system

    • B.

      Hydraulic system

    • C.

      Pneumatic system

    • D.

      Automation system

    Correct Answer
    C. Pneumatic system
    Explanation
    A pneumatic system is a fluid power system that utilizes air or another gas to transmit and control energy. It works by compressing the gas and using it to generate force or motion. Pneumatic systems are commonly used in industries such as manufacturing and transportation, where they are used to power tools, control valves, and operate machinery. They are preferred in certain applications due to their simplicity, cost-effectiveness, and ability to provide quick and precise movements.
