Mitsubishi Heavy Industries Interview Questions and Answers

Elongation is the amount of deformation a material undergoes before breaking. Friction is the force that opposes motion.

• Elongation is a measure of a material's ductility and is expressed as a percentage of the original length.

• Friction can be static or kinetic and is influenced by factors such as surface roughness and the force pressing the surfaces together.

• Examples of materials with high elongation include rubber and some plastics, while metals typically have lower elongatio...read more

Seal initiation temperature is the temperature at which a sealant or adhesive begins to bond to a surface.

• It is an important factor in determining the effectiveness of a sealant or adhesive.

• It varies depending on the type of sealant or adhesive being used.

• It can be affected by factors such as surface preparation and environmental conditions.

• For example, the seal initiation temperature for a silicone sealant may be around 40°C.

• If the surface temperature is below this temperatu...read more

Tensile strength is the maximum stress a material can withstand before breaking or fracturing.

• It is a measure of a material's ability to resist tension or stretching forces.

• It is usually expressed in units of force per unit of cross-sectional area.

• Examples of materials with high tensile strength include steel, titanium, and carbon fiber.

• Tensile strength is an important property in engineering and manufacturing, as it helps determine the suitability of a material for a particu...read more

Extrusion is a manufacturing process where a material is pushed through a die to create a continuous shape.

• It is commonly used in the production of plastic and metal products

• The process involves heating the material and then forcing it through a die using a screw or piston

• The resulting product can be a tube, rod, or other continuous shape

• Examples include PVC pipes, aluminum window frames, and plastic drinking straws

Yes, there are many types of polymer used in various industries.

• Polymers are large molecules made up of repeating units called monomers.

• They can be natural or synthetic.

• Examples of natural polymers include proteins, cellulose, and DNA.

• Examples of synthetic polymers include polyethylene, PVC, and nylon.

• Polymers are used in various industries such as packaging, construction, automotive, and electronics.
