  12. One Blue Scantron from ASNMSU (options A-J)

  13. What else do you need? X Rarely

  14. Why Not? Calculations don’t Always = understanding

  15. What else do you need? Curiosity

  16. Course Policies • Grading • 5-10 Clicker questions/day (scaled) = 25% • 2 Exams (100 points each) = 40% • 1 Comprehensive Final = 35% Above point system subject to minor changes

  17. Clicker Questions Beginning of class: 2-3 questions based on reading assignment During Class 3-7 questions based on lecture or on “Materials Moments”

  18. Extra Credit Opportunity The Materials Moment More information coming soon

  19. Grading Scale 90-100% = A 80-90% = B 70-80% = C 60-70% = D Below 60% = F Final Score = the higher of: • Average of all scores • Final Exam Score

  20. Important dates • Last Day to withdraw with a “W”: Tuesday, 11 March • Final Exam: Monday, 5 May 10:30-12:30 JH 283

  21. Borderline grades Extra credit and class participation move you up to the next letter grade.

  22. Attendance • Attendance is encouraged • Make-up exams • Written justification required • Must be taken in advance of assignment

  23. Clicker Policies • You may consult text or neighbors (unless instructed otherwise) • You must be present in class to vote • Lowest two clicker scores will be dropped to allow for forgotten/malfunctioning clickers. • No make-ups for clickers except for excused absences. (See syllabus.)

  24. Honesty Honesty is the only policy.

  25. Classroom Courtesy • Please be courteous w/ electronics • Participate in class discussions • Ask Questions

  26. PowerPoint Slides Posted on Canvas the morning before class

  27. Keys to SuccessHow many hours should you spendoutside of classto earn an A or B?

  28. Keys to SuccessBased on research on learning Take notes on reading assignment before coming to class (about 1 hour) Take notes in class on anything you don’t remember from textbook notes Spend 20 minutes MWF afternoon combining your two sets of notes (1 & 2) Over weekend, spend one hour reviewing your notes.

  29. Keys to Success, cont’d If you follow my advice, You spend 2 hrs 20 minutes per week.No need to cram for exams. The day before an exam, spend about 2 hours studying.

  30. The Course Scheduleexplained

  31. Because my major requires it. Because I live in a Material world. Because it is the most important course I will ever take. Why am I here?

  33. Reading Assignment for TodayCallister and Rethwisch Chapter 1–Motivation –Basics of Materials

  34. Definitions • Materials Science • Materials Scientist • Materials Engineering • Materials Engineer

  35. Interrelationships Composition Processing Structure Properties Performance

  36. Primary Classes of MaterialsComposition • Metals • Ceramics • Polymers • Composites

  37. Metals: High-carbon Steel High-Carbon Steel Jigsaw Blade

  38. Metals: Titanium “Obtanium” bicycle shocks vs. steel • Weight reduction • Longer life • Closer true-spring rate

  39. Ceramics: Tempered glass Tempered glass sink

  40. Ceramics: Borosilicates

  41. Ceramics: Refractories Silica refractory bricks: Industrial furnace

  42. Polymers: Vulcanized Rubber Ice hockey requires a hard disk of vulcanized rubber.

  43. Polymers: Thermoset Plastics Chemiplastica melamine thermoset plastics resistant to heat, chemicals, moisture, electricity and scratching.

  44. Polymers: Plasticizers Our plasticizers impart impact resistance, improve low-temperature flexibility of fused films and provide thermal and light stability.

  45. Composites Concrete reinforced with rebar

  46. Composites Fiberglass kayak

  47. Composites: Ceramic matrix Ceramic disc brakes: Ceramic rods in a ceramic matrix

  48. Interrelationships Composition Processing Structure Properties Performance

  49. Processing Processing determines properties Example: Raw timber vs. Paper

  50. ProcessingClay becomes Fired clay pottery
