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.

Q3. What is entropy and real life example
Ans. 
Entropy is a measure of disorder or randomness in a system.
• Entropy increases with time in a closed system

• A messy room has higher entropy than a clean room

• Melting of ice is an example of increase in entropy

• Burning of wood is another example of increase in entropy

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.

• Final...read more

Q2. Flywheel used in a engine
Ans. 
A flywheel is a mechanical device used in engines to store rotational energy and smooth out fluctuations in engine speed.
• Flywheels are typically made of steel or aluminum and are attached to the engine's crankshaft.

• They store energy during the power stroke and release it during the compression stroke to keep the engine running smoothly.

• Flywheels are also used in hybrid vehicles to store energy from regenerative braking...read more

Q3. Used of flywheel, crankcase, AVM pre filter
Ans. 
Flywheel, crankcase, and AVM pre filter are components used in internal combustion engines.
• Flywheel stores rotational energy and helps maintain engine speed during power strokes.

• Crankcase houses the crankshaft and other engine components.

• AVM pre filter is used to remove larger particles from the air before it enters the engine.

• These components are essential for the proper functioning of internal combustion engines.

Q2. Law of thermodynamics
Ans. 
The laws of thermodynamics describe how energy behaves in a system.
• First law: Energy cannot be created or destroyed, only transferred or converted.

• Second law: Entropy in a closed system will always increase over time.

• Third law: As temperature approaches absolute zero, the entropy of a system approaches a minimum value.

• Examples: A car engine converting fuel into motion follows the laws of thermodynamics.

• Examples: A refr...read more
