What is the least counting 9 main scale division are divided 10 equal parts in the vernier scale of caliper?

In measuring the diameter of a cylinder by this instrument, the main scale reads 35 divisions and the 4th division of vernier scale coincides with a main scale division. Find least count .

What is the length of 10 Division on the vernier scale?

9 mm
A vernier callipers has its main scale graduated in mm and 10 divisions on its vernier scale are equal in length to 9 mm. When the two jaws are in contact.

How do you find the least count of a main scale?

Mathematically a measurement instrument Least Count is calculated by dividing main scale reading by the total number of divisions on the main scale. And if the instrument also has a Secondary scale. Then instrument LC is the ratio of main scale L.C. and number of divisions on the secondary scale.

What is Vernier constant in physics?

Vernier constant is defined as the difference between the value of one main scale division and one vernier scale division. It is also known as the least count of vernier calliper i.e the minimum length that can be measured accurately using this instrument.

What is a scale division?

Scale Divisions A scale division is the smallest type of subdivision or unit that a scale’s digital display could indicate. It is a term that is commonly used with readability or resolution. Division could be determined by dividing the scale’s capacity by its readability.

What is vernier division?

One Vernier scale division (VSD) is the distance between two successive marks on the Vernier scale. It is given that 10 VSD = 9 MSD. Thus, 1 VSD = (9/10) MSD = 0.9 mm i.e., distance between two successive marks on the Vernier scale is 0.9 mm.

How do you calculate main scale reading?

How to Read a Linear Vernier Scale

1. Read the main scale. Look for the last whole increment visible before the 0 (zero) mark.
2. Read the secondary scale (Vernier) measurement. This is the division tick mark that lines up best with a mark on the main scale.
3. Add the two measurements together.

How will you measure the least count of vernier caliper Class 9?

Explanation: The formula of Vernier calliper least counts is determined by dividing the smallest reading of the main scale with the total number of vernier scale divisions. The LC of vernier calliper is the difference between one smallest main scale reading and one smallest vernier scale reading of 0.1 mm 0r 0.01 cm.
