Draw a neat labelled diagram of a vernier callipers. Name its main parts and state their functions.
Answer
A neat labelled diagram of a vernier callipers is shown below:
The main parts of the vernier callipers are as follows —
| Part | Function |
|---|---|
| Outside jaws | To measure the length of a rod, diameter of a sphere, external diameter of a hollow cylinder. |
| Inside jaws | To measure the internal diameter of a hollow cylinder or pipe. |
| Strip | To measure the depth of a beaker or a bottle. |
| Main scale | To measure length correct up to 1 mm. |
| Vernier scale | Helps to measure length correct upto 0.1 mm. |
