• FWM is commonly used in oceanography and coastal engineering.

• It involves the use of sensors and instruments to capture wave data.

• The data collected through FWM helps in understanding wave behavior and designing structures to withstand wave forces.

PTM stands for Precision Tooling and Manufacturing.

• PTM is an acronym for Precision Tooling and Manufacturing.

• PTM is a company that specializes in the design and production of precision tools and manufacturing equipment.

• PTM offers a wide range of services including CNC machining, tool and die making, and custom equipment fabrication.

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

• Consists of a main scale and a sliding vernier scale for more precise measurements

• Commonly used in engineering and machining for measuring lengths, diameters, and depths

• Can measure both internal and external dimensions

• Example: Measuring the diameter of a shaft or the thickness of a sheet metal

Maintaining 5s involves sustaining a system of organizing, cleaning, standardizing, and sustaining a workspace for efficiency and safety.

• Regularly sort and remove unnecessary items from the workspace

• Keep tools and materials organized and easily accessible

• Clean work areas daily to prevent clutter and improve safety

• Implement visual management techniques to maintain standards

• Train and involve all team members in 5s practices

A micrometer is a tool used for precise measurements in engineering and manufacturing.

• A micrometer is also known as a micrometer screw gauge.

• It is used to measure small distances or thicknesses with high accuracy.

• Micrometers are commonly used in mechanical engineering, machining, and quality control.

• Examples of micrometers include outside micrometers, inside micrometers, and depth micrometers.

Material properties refer to the characteristics and behaviors of materials under specific conditions.

• Material properties include mechanical, thermal, electrical, and chemical properties.

• Examples of material properties are strength, hardness, conductivity, and reactivity.

• Understanding material properties is crucial for designing and selecting materials for specific applications.

NPSH pump calculation is used to determine the minimum pressure required at the suction of a pump to prevent cavitation.

• NPSH stands for Net Positive Suction Head

• It is calculated by subtracting the vapor pressure of the fluid from the absolute pressure at the suction of the pump

• If the NPSH available is less than the NPSH required, cavitation can occur which can damage the pump and decrease its efficiency

Different types of brakes used in mechanical engineering.

• Mechanical brakes: rely on friction to slow or stop motion, such as disc brakes or drum brakes.

• Hydraulic brakes: use fluid pressure to apply force, commonly found in vehicles like cars and motorcycles.

• Electromagnetic brakes: use electromagnetic force to slow or stop motion, often used in industrial machinery.

• Regenerative brakes: convert kinetic energy into another form of energy, commonly used in hybrid and electric veh...read more

2s and 4s engines refer to 2-stroke and 4-stroke engines, each with their own advantages and disadvantages.

• 2-stroke engines have a power stroke every revolution, making them more powerful but less fuel efficient.

• 4-stroke engines have a power stroke every other revolution, making them more fuel efficient but less powerful.

• 2-stroke engines are simpler in design and lighter, but tend to produce more emissions.

• 4-stroke engines are more complex but offer better lubrication and dur...read more
