Visual Inspector Interview Questions and Answers for Freshers

Bearings are mechanical components that reduce friction between moving parts and support axial and radial loads.

• 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, tapered, or spherical rollers to reduce friction and support radial and axial loads.

• Plain bearings, also known as bushings, use a sliding motion to reduce fric...read more

An automobile is a motor vehicle designed for transportation on roads.

• It typically has four wheels and an engine.

• It is used for personal transportation, as well as commercial purposes.

• Examples include cars, trucks, buses, and motorcycles.

The differential is a device that allows wheels to rotate at different speeds while driving on a curve or turning.

• It helps to distribute power between the wheels

• It allows for smooth turning and prevents tire wear

• It is essential for four-wheel drive and all-wheel drive vehicles

There are many types of steel, each with different properties and uses.

• Carbon steel: contains varying amounts of carbon, used in construction and manufacturing

• Alloy steel: contains additional elements like nickel or chromium for improved strength and durability

• Stainless steel: contains chromium for corrosion resistance, commonly used in kitchen appliances and medical instruments

• Tool steel: designed for making tools, with high hardness and wear resistance

Tolerance refers to the acceptable range of variation in a measurement or dimension.

• Tolerance is the maximum allowable difference between the actual measurement and the desired measurement.

• It is important in manufacturing to ensure that parts fit together properly.

• For example, if a hole is supposed to be 1 inch in diameter with a tolerance of +/- 0.005 inches, the actual hole diameter can range from 0.995 inches to 1.005 inches.
