Ramsay Test Mechanical Maintenance 3

Question 1

In a hydraulic system, force is transmitted through:

Accepted Answer

An incompressible fluid under pressure

Answer

Hydraulics use pressurized incompressible fluid to transmit and multiply force.

Question 2

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

Accepted Answer

Cavitation from air or low suction

Answer

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

Question 3

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

Accepted Answer

Light oil

Answer

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

Question 4

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

Accepted Answer

Transmit torque while tolerating minor misalignment

Answer

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

Question 5

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

Accepted Answer

The micrometer needs to be zeroed/calibrated

Answer

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