6 Interview questions

A Quality Engineer was asked
Q. What are elongation and friction?
Ans. 

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...

A Quality Engineer was asked
Q. What is the seal initiation temperature?
Ans. 

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...

A Quality Engineer was asked
Q. What are the different types of extrusion?
Ans. 

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 stra...

A Quality Engineer was asked
Q. Copolymer and homopolymer difference
Ans. 

Copolymers are made of two or more different monomers, while homopolymers are made of a single monomer.

  • Copolymers have improved properties compared to homopolymers due to the combination of different monomers.

  • Homopolymers have a more uniform structure and properties compared to copolymers.

  • Examples of copolymers include styrene-butadiene rubber and acrylonitrile-butadiene-styrene, while examples of homopolymers inc...

A Quality Engineer was asked
Q. There are many types of polymer
Ans. 

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

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

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

A Quality Engineer was asked
Q. What is tensile strength
Ans. 

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...
