FREE Caliper Vernier Measurement Questions and Answers

Question 1

What measurement(s) below cannot be taken with a vernier caliper?

Accepted Answer

Measuring the height of a tower

Answer

A Vernier caliper is a precision instrument designed for measuring small dimensions, typically up to a few hundred millimeters or several inches. It is used for internal, external, depth, and step measurements of objects. Measuring the height of a tower, which is a large-scale measurement, is far beyond the practical range and capability of a Vernier caliper, requiring tools like a tape measure, laser distance meter, or surveying equipment.

Question 2

What is the name of the component in the diagram labeled B?

Accepted Answer

Internal jaws

Answer

In a typical caliper diagram, the component labeled 'B' refers to the internal jaws. These are the smaller, upper jaws designed specifically for measuring the internal dimensions of an object, such as the diameter of a hole or the width of a slot. They are distinct from the larger outside jaws used for external measurements.

Question 3

The red line indicates the coinciding lines. What measurement do you have?

Accepted Answer

15.46 cm

Answer

To read a Vernier caliper, first identify the main scale reading just before the zero mark of the Vernier scale, which is 15.4 cm. Then, find the line on the Vernier scale that perfectly aligns with a line on the main scale; if this is the 6th division and the least count is 0.01 cm, it adds 0.06 cm. Adding these values gives a total measurement of 15.4 cm + 0.06 cm = 15.46 cm.

Question 4

What is the best answer?

Accepted Answer

1,55 mm

Answer

To determine the measurement, first read the main scale value just before the Vernier scale's zero mark. If this is 1.5 mm, then identify the Vernier scale division that perfectly aligns with any main scale division. If the 5th Vernier mark aligns and the least count is 0.01 mm, this adds 0.05 mm to the reading. Therefore, the total measurement is 1.5 mm + 0.05 mm = 1.55 mm.

Question 5

What is the minor count of the standard metric vernier caliper?

Accepted Answer

0.02mm

Answer

The 'minor count' is synonymous with the least count of a measuring instrument, representing the smallest measurement it can accurately resolve. For a standard metric Vernier caliper, the most common and widely used least count is 0.02 mm. This precision allows for detailed measurements in various technical applications.
