Q2. Factor of safety
Ans. 
Factor of safety is the ratio of the maximum stress a material can withstand to the actual stress it is subjected to.
• It is used to ensure the safety and reliability of a design.

• It is calculated by dividing the ultimate strength of a material by the maximum stress it is expected to experience.

• A higher factor of safety indicates a more reliable design.

• Factors of safety vary depending on the application and industry.

Q4. What is Otto cycle
Ans. 
Otto cycle is a four-stroke combustion cycle used in spark-ignition engines.
• It consists of four processes: intake, compression, power, and exhaust.

• During the intake stroke, the fuel-air mixture is drawn into the cylinder.

• In the compression stroke, the mixture is compressed to a high pressure and temperature.

• The power stroke is where the spark plug ignites the mixture, causing it to expand and push the piston down.
