Ramsay Test Maintenance 3 — Questions and Answers
Question 1: When using a hydraulic system, what does the fluid primarily transmit?
- Force and motion (Correct answer)
- Heat only
- Electrical current
- Sound waves
Correct answer: Force and motion
Hydraulic fluid transmits force and motion through an incompressible liquid.
Question 2: A V-belt drive is slipping under load. Which adjustment most directly addresses this?
- Increase belt tension or replace a worn belt (Correct answer)
- Add oil to the belt surface
- Reduce the motor voltage
- Remove one of the sheaves
Correct answer: Increase belt tension or replace a worn belt
Slipping is usually caused by low tension or a worn, glazed belt.
Question 3: What is the function of a fuse in an electrical circuit?
- To protect the circuit by breaking it during overcurrent (Correct answer)
- To increase the voltage
- To store electrical charge
- To smooth out current ripple
Correct answer: To protect the circuit by breaking it during overcurrent
A fuse melts and opens the circuit when current exceeds a safe level.
Question 4: Misalignment between a motor and pump coupling most commonly causes what problem?
- Excessive vibration and premature bearing wear (Correct answer)
- Higher fuel efficiency
- Lower operating temperature
- Increased belt life
Correct answer: Excessive vibration and premature bearing wear
Coupling misalignment creates vibration that wears bearings and seals quickly.
Question 5: Which gauge is used to check the clearance between two mating parts, such as valve tappets?
- Feeler gauge (Correct answer)
- Pressure gauge
- Strain gauge
- Bourdon tube
Correct answer: Feeler gauge
A feeler gauge measures small gaps and clearances between parts.
Question 6: In a gear system, what is the main reason for using a lubricant?
- To reduce friction and wear between meshing teeth (Correct answer)
- To increase the gear ratio
- To change the rotation direction
- To insulate against electricity
Correct answer: To reduce friction and wear between meshing teeth
Lubrication reduces friction, heat, and wear where gear teeth mesh.
Question 7: A reading of 'open circuit' on a multimeter continuity test of a wire indicates what?
- A break in the wire path (Correct answer)
- A perfectly good connection
- Excess voltage present
- Correct grounding
Correct answer: A break in the wire path
No continuity (open) means the electrical path is broken somewhere.
