Preparation for MSE 280 – Engineering Materials Test 1 (Chapters 1, 2, 3, 4, and 6) Examination questions will be multiple choice, essay/problem, short answer and /true-false. Don’t forget about the calculator policy (see the syllabus). You must show work and units throughout your solution. The following information is given to help you prepare for the test. I may have forgotten some material so please use your notes as a complete guide. There are far more questions given below than anyone could answer in the class period – they have come from many offerings of similar courses. Some topics and questions may be are redundant. Areas for Questions 1. Determine if bonding will be metallic, covalent, or ionic and the characteristics of each bond type 2. Strength of primary versus secondary bonds 3. Energy and force versus distance plots for materials. How does melting point generally affect these curves? Where do bond strength, and mean distance come from? What do thermal expansion and elastic modulus have to do with them? 4. Difference between glasses (amorphous materials) and crystals 5. Very basics of crystals 6. Definitions of alloys, solid solutions and compounds (particularly ceramics) 7. What are point defects, line defects, and planar defects? 8. Definitions of allotropy and polymorphism 9. Definitions of engineering stress, engineering stain, elongation to failure, Young's modulus, Poisson's ratio, necking, offset yield strength, tensile strength, true stress, true strain 10. Strengthening mechanisms 11. Fundamentals of a tensile test, bend test, hardness testing, impact testing. What information do you get from each? What do the specimens look like? 12. Schematic stress-strain curves for various materials 13. DBTT and material differences. Old Questions of Similar Nature Old Questions of Similar Nature Introduction to MSE (Ch.1) 1. What is a composite material? 2. What is a semiconductor? 3. What is a ceramic? 4. What is a thermoplastic polymer? What happens to a thermoplastic polymer when it is heated and reheated? 5. What is a thermoset polymer? What happens to a thermoset polymer when it is heated and reheated? Atomic Structure (Ch. 2) 1. In a covalently bonded material, electrons are effectively transferred between atoms, with the high electronegativities element giving up the electrons. (T/F) 2. The major bonding type(s) in polymers are: a. ionic b. covalent c. metallic d. secondary e. none of the above 3. The major bonding type(s) in metals are:
