Total questions: 20
Worksheet time: 10mins
Gauges are primarily used for:
Measuring voltage
Checking whether parts meet dimensional limits
Cutting excess material
Calibrating micrometers
Which of the following is an advantage of using gauges?
Can be used by less skilled workers
Provides actual readings
Gives detailed part condition
Requires electrical power
A major disadvantage of gauges is that they:
Are too light
Provide no actual measurement reading
Are non-portable
Are inexpensive
The most important factor when selecting materials for gauges is:
Hardness to resist wear
Low density
High conductivity
High elasticity
Which material provides the greatest wear resistance?
High carbon steel
Tungsten carbide
Ceramics
Chromium plating
In a limit gauge, the “Go” member is used to:
Check the lower limit (minimum size)
Check the upper limit (maximum size)
Identify oversize parts
Verify roundness
The “No Go” member in a gauge is typically:
Marked in red for easy identification
Marked in blue for easy identification
Marked in green for easy identification
Marked in yellow for easy identification
Hole gauges are used to:
Quickly determine the diameter of drills or rods
Check internal threads
Measure surface roughness
Check external diameters
The knife-edge or straight-edge gauge is used to test:
Flatness and straightness
Roundness
Thread pitch
Hole diameter
A feeler gauge is mainly used to:
Measure clearance or gap between two parts
Check internal thread limits
Measure outer diameters
Test surface hardness
The light-gap method is used in:
Radius/Fillet gauge inspection
Micrometer reading
Surface roughness checking
Vernier caliper measurement
The “Go” end of a limit plug gauge represents:
Minimum dimension (lower limit)
Maximum dimension (upper limit)
Average tolerance
Nominal dimension
If the “No Go” member of a plug gauge enters the hole, it means:
Hole is undersized
Hole is oversized
Hole is within limits
Gauge is faulty
14. A limit ring gauge is used to check:
the external diameter of a cylindrical object
the internal diameter of a hole
the length of a shaft
the surface finish of a component
Which of the following is a limitation of ring gauges?
Cannot detect out-of-roundness
Cannot measure length
Cannot detect taper
Cannot check threads
Snap gauges are used to check:
Outside diameter or thickness of a part
Internal diameter
Thread pitch
Depth of hole
In a snap gauge, the “No Go” member checks the:
Minimum dimension (lower limit)
Maximum dimension
Center alignment
Surface roughness
A thread plug gauge is used for:
Internal threads
External threads
Taper holes
Flat surfaces
A thread ring gauge is used to check:
External thread accuracy
Internal thread accuracy
Depth of a hole
Surface hardness
According to Taylor’s Principle of Gauging, the “Go” member should:
Check as many dimensions as possible
Check only one dimension
Be used for final finishing
Measure average tolerance
