Precision Measuring Tools Quiz

What is the primary use of a Vernier caliper?

• To measure the depth of holes

• To measure internal and external dimensions accurately

• To check the level of surfaces

• To measure pressure in hydraulic systems

Which part of the dial indicator shows the measurement reading?

• The spindle

• The dial face

• The locking lever

• The base

What is the typical use of a feeler gauge?

• To measure the thickness of gaps or clearances

• To determine the diameter of small objects

• To measure the depth of holes or slots

• To check the flatness of surfaces

How is accuracy maintained in an outside micrometer?

• By calibrating it with a standard gauge block

• By adjusting the dial indicator regularly

• By using a Vernier scale

• By applying consistent force through a ratchet mechanism

What does the Vernier scale on a Vernier caliper help with?

• Increasing the tool's range

• Measuring angles

• Improving measurement accuracy

• Providing a digital output

Which component of a dial indicator moves in response to small changes in height?

• The base

• The dial

• The spindle

• The locking lever

Feeler gauges are primarily made from what material?

• Plastic

• Stainless steel

• Aluminum

• Brass

What is the main advantage of using an outside micrometer over a Vernier caliper?

• It can measure larger dimensions.

• It is more portable.

• It provides higher precision.

• It is easier to read.

In a Vernier caliper, the difference between one main scale division and one Vernier scale division is known as what?

• The pitch

• The least count

• The calibration constant

• The Vernier constant

What is the purpose of the ratchet on an outside micrometer?

• To lock the spindle in place

• To adjust the dial indicator

• To ensure uniform measuring force

• To change the measurement units
