Presentation Transcript

  1. ME495 Philosophy • First a commercial message: Starting this moment, take notes, because some group will be summarizing at beginning of next lecture. • Important ppt slides (with ME 495 logo on bottom) are posted on web. Check a few hours before lecture to get latest copy. • Come to class on time

  2. YOUNG·MAN·IF·THEORY AND·PRACTICE·DIFFER USE·YOUR·HORSE·SENSE Joseph·Baker·Davis UM Student 1864-Assoc Dean 1910

  3. ME495 Corollary "Engineering is the art of modeling materials we do not wholly understand, into shapes we cannot precisely analyze so as to withstand forces we cannot properly assess, in such a way that the public has no reason to suspect the extent of our ignorance."   Attributed to Dr. A. R. Dykes, British Institution of Engineers.

  4. Goals and links • Develop horse sense • Practice ‘back of envelope’ calculation • Develop test procedures • Learn DOE • Deal with error! • Integrate • tech comm • engineering science as much as possible • economics • Think outside the box…

  5. Error • Bad: F=1213.677 • OK: F=1213.677 lb • Better F=1213.677 + 219.455 lb • Best F=1200 + 200 lb

  6. Complaints from students   No wishy-washy answersProblems are too open-endedFaster evening email response timeLectures don’t tell us anythingThere is too much to absorb in lecturesI left Schultz’s office hours with more questions than answersBut Prof. DiGiovanni said….Differences in TC of 395/495Quizzes and Reviews were meaninglessIf the equations we learned in the first three years do not work, do not use them.

  7. Complaints from TA/Prof Students come to lab unprepared Tardiness and poor attendance Students come into my office and ask, “What exactly do you want us to do with…” The students are in minimalist mode Students do not check the ‘reasonableness’ of their answers.

  8. Past labs…

  9. 3 Labs this spring   MufflersInjection molding | Cooling 1070 AL 1000GGB | 2052 AL switch groups

  10. Where do I go?

  11. Engineering Trivial Pursuit Rules No reference booksNo calculatorsNo slide rulesNo multiple-choice questionsNo lifelinesNo extended precision answers Our goal today… The big and the small

  12. How much does this structure weigh? • How much area does a bit require on a CD? • You have 10 minutes!
