An important chapter I guess, not from exam point of view, but at least good knowledge of the subject and its necessity is necessary to keep you going forward. The study material is really good for telling you the importance but Vanblack puts it in a much better way saying "Engineers adapt materials and energy to society's needs". Cool way right.
So basically we need to learn the following topics in this chapter as per me
- Definition and importance of the subject
- What are Engineering materials. Should be able to write short notes on the types of materials listed viz Metals and alloys, Polymers, Ceramics, Composites, Bio materials,..
- Must be able to tell examples of each of above type and also justify the same.
The prospects of making marks from this chapter are really bleak. I went through 6 or 7 old question papers only to find one question from this chapter. The question too was cool saying " Classify the materials given below and write reasons." The materials in question are RCC, Wood, Rubber, Cast Iron, Brick. Pretty simple.
But there is something confusing, what is concrete?? I mean is it a ceramic or a composite. Everywhere ( on web or in text books ) I find that its a composite but in the study material provided by AMIE, it is named as ceramic. Should look into this point.
I am done with this chapter by 7 / 11 / 2010. This is cool stuff man.

Don't forget to grab a copy of Material Science and Engineering book, which is essential for preparing for AMIE, Material Science.
