Vernier Callipers: Dimensions of Regular Body

The experiment is called “Vernier Callipers: Dimensions of Regular Body“.

In this experiment, we will use Vernier callipers, a tool that helps us measure lengths accurately, to find out the size of a specific regular object that we know the mass of. By doing this, we can figure out how tightly packed the material is inside the object, which tells us its density.

Let’s understand some important points regarding this experiment:

Regular Body

A “regular body” refers to an object or shape that has uniform or consistent features and sides. Examples of regular bodies include cubes, spheres, cylinders, and prisms, where all sides and angles are the same.

Volume

Volume refers to the amount of space occupied by an object or substance in three dimensions.

Density

Density is a measure of how much mass (or material) is packed into a given volume.

Density = Mass / Volume

Important terms regarding Vernier Calliper:

Main Scale

The big, unmovable scale on the Vernier Calipers is the main scale. It gives you the main number part of your measurement and helps you put the callipers in the right spot for good measurements.

Vernier Scale

The Vernier scale is a smaller scale that moves next to the main one. It helps you read the little bit extra that the main scale doesn’t cover.

Jaws

The jaws are the parts of the Vernier callipers that touch the thing you’re measuring. There are two sets: one on top and one on the bottom. The top one doesn’t move, but the bottom one can slide along the big scale.

Tail

The tail or depth rod is a protrusion on the back end of the vernier calliper, perpendicular to the main scale. It is used to measure the depth of small holes, grooves, or depth of small things accurately.

Least Count

The least count is the smallest measurement you can read from the Vernier Calipers. To find it, you divide the size of one main scale division by how many small divisions there are on the Vernier scale.
