Q1. Different between 2 stroke and 4 stroke engine ?
Ans. 
2 stroke and 4 stroke engines differ in their operation and design, with variations in the number of strokes, power output, and fuel efficiency.
• 2 stroke engines complete a power cycle in 2 strokes of the piston, while 4 stroke engines complete it in 4 strokes.

• 2 stroke engines have a simpler design with fewer moving parts, making them lighter and more compact.

• 4 stroke engines have separate intake, compression, power, an...read more

Q2. 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 of a micrometer is determined by the number of divisions on the thimble and the pitch of the screw.

• The formula to calculate the least count is: Least Count = Pitch / Number of divisions on the thimble.

• For example, if the pitch of the screw is 0.5 mm and there are 50 divisions on the thimble, t...read more

Q3. What is heat treatment?
Ans. 
Heat treatment is a process used to alter the physical and mechanical properties of materials through heating and cooling.
• Heat treatment involves heating a material to a specific temperature and holding it at that temperature for a certain period of time.

• The purpose of heat treatment is to change the material's microstructure, which in turn affects its hardness, strength, toughness, and other properties.

• Common heat tre...read more

Q4. What is 6 s?
Ans. 
6 s is the abbreviation for 6 sigma, a statistical measure of quality control in manufacturing processes.
• 6 s refers to the Six Sigma methodology used in process improvement.

• It aims to reduce defects and variations in manufacturing processes.

• Six Sigma uses statistical analysis and data-driven approaches to achieve high levels of quality.

• It focuses on minimizing process variation to improve efficiency and customer satisf...read more
