This set of Engineering Materials Science "Multiple Select Questions & Answers" are based on “CLASSIFICATION OF MATERIALS”
CLASSIFICATION OF MATERIALS
Multiple Select Questions (MSQ)
Hello reader, here you can find some MSQ with answers. But before reading this I will suggest you take a practice test on these questions given below. so you can understand your strength on this topic.
Click here to go Practice Test section on this topic namely Classification of Materials.
But if you want to read this topic first and then practice it then read it carefully. The Multiple Select Questions (MSQ) based on Classification of Materials are given below:
1) In terms of which of the following properties, metals are better than ceramics?
Correct Answer is " B", "C", "D"
Metals have greater ductility, density, and electrical conductivity than ceramics. The stiffness of ceramics is comparable to metals.
2) Which of the following is/are not the property of polymer?
Correct Answer is "A", "C", "D"
Polymers have high molecular weight but they are generally ductile in nature. Polymer shows non-newtonian behavior and they have very low electrical conductivities.
3) Example of ceramics are
Correct Answer is "A", "B", "C"
Alumina, Silica & Porcelain are ceramics but Kevlar (aromatic polyamide) is a polymer.
4) CFRP are used in
Correct Answer is "A", "B", "C", "D"
CFRP(Carbon Fibre Reinforced Polymer) is a composite used in high-tech sporting equipment like bicycles, golf clubs, tennis rackets, skis, etc.
5) Composite materials are
Correct Answer is "A", "D"
The density and Conductivity of metal are higher than ceramics and polymer. The strength and Stiffness of metals and ceramics are comparable and are higher than polymer.
Do u read all the questions and answers given above carefully? let's make a practice on all the questions given above.
