Vernier Scale Measurement Concepts

This video tutorial explains how to read a vernier scale using a vernier height gauge. It covers the main and vernier scales, detailing how to take initial readings from the main scale and secondary readings from the vernier scale. The tutorial demonstrates the process of aligning the scales and calculating the final measurement by combining readings from both scales.

What are the two main components of a vernier scale?

• Zero point and graduation marks

• Main scale and sliding scale

• Metric scale and inch scale

• Inch scale and centimeter scale

When taking the first set of readings, which part of the vernier scale is ignored?

• The sliding scale

• The vernier scale numbers

• The zero point

• The main scale

How is the main scale broken down in terms of measurements?

• Into meters and decimeters

• Into inches and fractions of an inch

• Into centimeters and millimeters

• Into feet and yards

What is the finest graduation on the main scale?

• 0.5 inch

• 0.05 inch

• 0.01 inch

• 0.1 inch

What is the next step after completing readings from the main scale?

• Adjust the zero point

• Switch to the vernier scale

• Re-read the main scale

• Re-calibrate the main scale

What is the 'point of coincidence' on a vernier scale?

• Where the scale ends

• Where a line on the vernier scale aligns with a line on the main scale

• Where the main scale and vernier scale start

• Where the zero point is located

Which method is used to find the point of coincidence?

• Scale method

• Alignment method

• Bracket method

• Zero method

What is the final step in calculating the total measurement?

• Adding the vernier reading to the main scale reading

• Subtracting the vernier reading from the main scale reading

• Multiplying the vernier reading by the main scale reading

• Dividing the vernier reading by the main scale reading

What is the total measurement if the main scale reads 1 inch 450 thousandths and the vernier scale reads 22?

• 1 inch 500

• 1 inch 450

• 1 inch 422

• 1 inch 472

What is the purpose of the vernier scale in measurement?

• To replace the main scale

• To measure in metric units

• To offer a second set of readings for precision

• To provide a rough estimate
