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

Fishbone diagram is a visual tool used to identify the possible causes of a problem or an effect.

• Also known as Ishikawa diagram or cause-and-effect diagram
