Maximum material condition (MMC) is a term used in engineering to describe the condition of a part when it contains the maximum amount of material allowed by its design specifications.

• MMC is the condition where a part has the maximum amount of material within the specified limits.

• It is used to ensure proper fit and function of mating parts.

• GD&T symbols are used to indicate MMC on engineering drawings.

• For example, a hol...read more

Lest material condition refers to the worst possible condition that a material can be in without being rejected.

• Lest material condition is used to establish the minimum acceptable quality level for a material.

• It helps in determining the point at which a material should be rejected due to poor quality.

• Examples include maximum allowable defects in a material or minimum strength requirements.

A vernier caliper is a precision measuring tool used to measure internal and external dimensions with high accuracy.

• Consists of two main parts - the main scale and the vernier scale

• The main scale is fixed and has markings in millimeters or inches

• The vernier scale slides along the main scale and provides more precise measurements

• Other parts include the jaws (for measuring external dimensions), the depth gauge (for measu...read more

The fuel pump is responsible for delivering fuel from the gas tank to the engine at the correct pressure.

• The fuel pump is typically located inside the fuel tank.

• It is powered by electricity and uses a diaphragm or impeller to create pressure.

• The fuel pump ensures that the engine receives the right amount of fuel for combustion.

• Issues with the fuel pump can lead to poor engine performance or stalling.

• Regular maintenance...read more

Fuel injectors play a crucial role in controlling the fuel flow rate in an engine, measured in feet per minute (fpm).

• Fuel injectors are responsible for delivering the right amount of fuel to the engine cylinders at the right time.

• The flow rate of fuel through the injectors is measured in feet per minute (fpm) to ensure optimal engine performance.

• Correlation between fuel injector performance and fpm can indicate efficie...read more
