  1. In a hydraulic system, force is transmitted through:

    Answer: An incompressible fluid under pressure

    Hydraulics use pressurized incompressible fluid to transmit and multiply force.

  2. A pump that fails to prime and makes a rattling noise is likely experiencing:

    Answer: Cavitation from air or low suction

    Cavitation occurs when air or vapor bubbles form and collapse due to poor suction.

  3. Which lubricant type is generally best for high-speed, low-load bearings?

    Answer: Light oil

    Light oil reduces drag and dissipates heat better than grease at high speeds.

  4. The primary function of a coupling between a motor and a pump is to:

    Answer: Transmit torque while tolerating minor misalignment

    Couplings connect shafts to transmit rotational power and absorb slight misalignment.

  5. A micrometer reads 0.250 inch when the spindle is closed against the anvil. This means:

    Answer: The micrometer needs to be zeroed/calibrated

    A closed micrometer should read zero; any other value indicates a calibration error.

  6. What does a feeler gauge measure?

    Answer: The clearance gap between two surfaces

    Feeler gauges are thin blades used to measure small gaps and clearances.

  7. When chain drive is too loose, the typical symptom is:

    Answer: Chain whip, jumping, or skipping sprocket teeth

    A loose chain can whip, jump teeth, and wear sprockets prematurely.
