Q1. What is the least count of Micrometer
Ans. 
The least count of a micrometer is the smallest measurement that can be accurately read on the micrometer scale.
• The least count is determined by the number of divisions on the micrometer scale and the pitch of the screw.

• It is usually expressed in micrometers or millimeters.

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

Q2. What is type of defect in bearing?
Ans. 
The types of defects in bearings include wear, corrosion, pitting, cracking, and misalignment.
• Wear: Occurs due to friction and can lead to loss of material and increased clearance.

• Corrosion: Caused by chemical reactions, leading to surface degradation and reduced performance.

• Pitting: Localized surface damage caused by fatigue or contaminants, resulting in roughness and reduced load-carrying capacity.

• Cracking: Can occur...read more

Q3. What is the face grinding
Ans. 
Face grinding is a machining process used to achieve smooth and precise surfaces on the face of a workpiece.
• Face grinding involves removing material from the face of a workpiece using a grinding wheel.

• It is commonly used in manufacturing industries to improve the flatness, parallelism, and surface finish of components.

• The process can be performed manually or using automated grinding machines.

• Face grinding is often used...read more

Q4. What is type of bearing?
Ans. 
A type of bearing is a device that supports a rotating shaft and reduces friction between moving parts.
• Bearings are used in various mechanical systems to enable smooth and efficient movement.

• There are several types of bearings, including ball bearings, roller bearings, and plain bearings.

• Ball bearings use balls to reduce friction and support radial and axial loads.

• Roller bearings use cylindrical or tapered rollers to s...read more
