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

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.

Thermodynamic processes are various ways in which energy can be transferred to or from a system.

• Isothermal process: constant temperature

• Adiabatic process: no heat transfer

• Isobaric process: constant pressure

• Isochoric process: constant volume

• Examples: carnot cycle, rankine cycle, stirling cycle

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.

• Finally, in the exhaust stroke, the spent gases are expelled fr...read more

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.

• For example, a factor of safety of 2 is common in civil enginee...read more
