The least count of a micrometer is the smallest measurement that can be read on the micrometer scale.

• The least count of a micrometer is determined by the number of divisions on the thimble and the pitch of the screw.

• It is usually expressed in micrometers or millimeters.

• For example, if a micrometer has 50 divisions on the thimble and the pitch of the screw is 0.5 mm, then the least count would be 0.01 mm (0.5 mm / 50 di

The least count of a vernier caliper is the smallest measurement that can be read on the scale.

• The least count is determined by the number of divisions on the main scale and the vernier scale.

• It is calculated by dividing the smallest division on the main scale by the total number of divisions on the vernier scale.

• For example, if the smallest division on the main scale is 0.1 mm and the total number of divisions on the ...read more

Backlash is the play or movement between mechanical components due to gaps or clearances.

• Backlash refers to the amount of movement or play that occurs between two mechanical components.
