- Q1. 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 it h...
- Q2. What is extrusion type
- 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 straws
- Q3. What is 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 arou...
- Q4. What is 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 and ...
- Q5. There are many types of polymer
- Ans.
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.
- Q6. 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 include
