Tsugami Precision Engineering Graduate Engineer Interview Questions, Process, and Tips

Aerodynamics is the study of how gases interact with moving objects, particularly in relation to air flow and resistance.

• Aerodynamics is crucial in designing vehicles like airplanes, cars, and bicycles to reduce drag and improve efficiency.

• It involves studying factors such as lift, drag, thrust, and weight to optimize the performance of vehicles.

• Aerodynamic principles are also applied in sports equipment like golf ball...read more

Hydrodynamics is the study of fluids in motion, including the forces and energy involved.

• Hydrodynamics deals with the behavior of liquids and gases in motion.

• It involves studying the forces acting on fluids and the energy transfer within them.

• Applications include designing ships, airplanes, and understanding weather patterns.

• Key concepts include Bernoulli's principle, viscosity, and turbulence.

Types of laser cuttings include vaporization cutting, melt and blow cutting, thermal stress cracking, and scribing.

• Vaporization cutting: material is heated until it vaporizes

• Melt and blow cutting: material is melted by the laser beam and blown away by a gas jet

• Thermal stress cracking: material is heated until it cracks

• Scribing: material is partially melted to create a groove

Archimedes principle states that the buoyant force on an object is equal to the weight of the fluid displaced by the object.

• Buoyant force is the upward force exerted by a fluid that opposes the weight of an immersed object.

• The principle explains why objects float or sink in a fluid based on their density.

• For example, a ship floats because it displaces enough water to equal its weight, while a dense object like a rock s

HMC stands for Horizontal Machining Center and VMC stands for Vertical Machining Center.

• HMC is a machine tool used for high precision machining of a wide range of materials in industries like automotive, aerospace, and mold making.

• VMC is also a machine tool used for precision machining, but the spindle is oriented vertically, allowing for easy access to the workpiece.

• Both HMC and VMC are commonly used in manufacturing ...read more
