Question

Name the part of the vernier callipers which is used to measure the following first external diameter of a cube second internal diameter of a mug third depth of a small bottle fourth thickness of a pencil

Answer 1

Answer:  Answer to the questions is

1) External jaws

2) Internal jaws  

3) Depth measuring blade.

Explanation:

                    Vernier calipers is a scale like precision equipment used to measure diameters,distances and depths accurately. It consists of a metric &/or imperial scale which has a moving scale upon it (smaller than the original scale).

                     This moving scale has a locking screw which helps it to be fixed in position. Bigger scale has one end of jaws and the moving scale has the other end of the jaws. and there is a thin blade like structure attached to the back of moving scale which helps in measuring the depth.

                       The least count of the Vernier calipers is 0.1 mm, which means it can measure accurately up to 0.1 mm.

Answer 2

The following parts of the vernier callipers are used to measures the given dimensions

• The lowers jaws are generally used for measuring external diameters such as cube
• The inner or upper jaws present on the vernier callipers are used to find internal diameter of mug
• The depth rod of vernier callipers is used to find the depth of objects such as water bottles

• The lower jaws present in the vernier callipers is used to measure the external diameter or thickness of pencils etc...
