Lab 3 grades Lab 4 grade averages wws hp tb sg mc
Lab 3 Feedback • No sample calculations • Executive Summ/Intro/Conclusion Repetition • Testing of ejection temp, brittleness • Young’s Modulus errors • Significant digits • Safety factor, Angle in torque equations • Injection rates vs. fill time • Use of correlation coefficients • Weld lines in gears • ‘freeze’ or ‘solidifying’ times • importance of air pockets • Shultz
Lab 4 Oral Feedback • Very few effectively pointed • Basically, only 3 people used ‘basically’ • Phase diagram questions • Think outside the box • Cost concerns • What is the hardest constraint to satisfy? • What is ideal (serving, storing) temp? • What is meant by optimization? • Shultz
