Hydraulic fluid transmits force and motion through an incompressible liquid.
A V-belt drive is slipping under load. Which adjustment most directly addresses this?
Answer: Increase belt tension or replace a worn belt
Slipping is usually caused by low tension or a worn, glazed belt.
What is the function of a fuse in an electrical circuit?
Answer: To protect the circuit by breaking it during overcurrent
A fuse melts and opens the circuit when current exceeds a safe level.
Misalignment between a motor and pump coupling most commonly causes what problem?
Answer: Excessive vibration and premature bearing wear
Coupling misalignment creates vibration that wears bearings and seals quickly.
Which gauge is used to check the clearance between two mating parts, such as valve tappets?
Answer: Feeler gauge
A feeler gauge measures small gaps and clearances between parts.
In a gear system, what is the main reason for using a lubricant?
Answer: To reduce friction and wear between meshing teeth
Lubrication reduces friction, heat, and wear where gear teeth mesh.
A reading of 'open circuit' on a multimeter continuity test of a wire indicates what?
