Prerequisite: Chemistry 101 and concurrent enrollment in Physics 101 recommended. 

Course Description: Investigation of the internal structure of metals, ceramics, polymers, composites and semi-conducting materials and their effect on mechanical, electrical, magnetic and thermal properties.  Laboratory investigations include metallography, tensile/compression test and heat treat analysis.  Field Trips required.  Lecture: 2 hours. Lab 3 hours.  Discussion 1 hour.

Please note the on-line published schedule did not list the lecture time correctly.  The class ends at 12:35, not 12:25 p.m.  The class is scheduled as follows Due to the loss of 10 minutes per lecture, I will lecture 20 minutes at the beginning of each lab period.

COURSE OBJECTIVES:

1.  Understand how the structure of materials affects their properties.

2.  Develop a working knowledge of the three primary engineering materials (ceramics, polymers, metals).

3.  Develop analytical and empirical data acquisition and analysis skills through material laboratories.

 

REQUIRED TEXT:   Materials Science and Engineering by William D. Callister, Sixth Edition.

 

Equipment and Attire: For the lab, safety goggles are recommended.  Students should wear closed-toe shoes.  Aprons or lab coats are recommended; expensive clothes are not.

Calculators should include natural and common logarithms, ex, and trigonometric functions. 

 

GRADING: The following point distribution is approximate

Discussion Problems - 10 sets X 5 points/set   =   50 points      6 %

Quizzes – 11 Quizzes X 10 points/Quiz                 = 110 “            13

Test  -    3 Test X 100 points/test                            = 300                   35

Final test – 150 points                                         = 150                   18

Labs – 11 Experiments X 20 points/exp                  = 220                   26

Field Trip Report                                                 =   15                 2

Total Points                                                         = 845

Assignments:  Homework will not be assigned and graded.  Homework turned in up to 24 hours late will have a 20% deduction.  After 24 hours a late homework will not be accepted (underlined text added later)., but not graded.  The wise student will work the problems to be better prepared for test and quizzes.  The lowest quiz and lab grade will be dropped (if you are absent, the missed assignment will be dropped, assuming you notify me by phone or email of your absence). 

 

Grades will be based on the following scale:

90.0 %   ≤ A 

80.0       ≤ B < 90.0

70.0       ≤ C < 80.0

60.0       ≤ D < 70.0

F                   < 60.0

 

Attendance:  Students are expected to be punctual and attend classes regularly.  It is in your interest for success in this course to attend all lectures and labs.  If you are absent a total of 12 or more hours (2 weeks), you may be dropped.  To drop you need to fill out a form at the Admissions and Records office.  If you do not officially drop, and I forget to drop you, you will receive an F in the class. 

 

            Students are responsible for work missed during absences.  Please notify me by phone or email of your absence if you do not wish to be dropped.  If you wish to avoid a zero on any assignments missed, provide a written reason for the absence.  No make-up exams will be given.  Upon approval for an absence of an exam, the points missed will be added to the value of the final exam.

 

Grade Corrections: If you feel any of your work was graded incorrectly, you make express this in writing to the professor within two class meetings after the return of your work.  No re-grading will be done after two class meetings. 

 

Cheating: Cheating is trying to get a better grade without earning the grade.  By cheating you are dishonestly trying to get a grade that other students are working hard to earn.  I view your cheating as you stealing from other students.  This dishonest behavior comes in many forms including copying lab reports, homework or tests, using a “cheat sheet” on a test, plagiarizing (copying without giving credit), text messaging using a phone or calculator, etc. At a minimum, a zero will be given for the work in question.  More serious forms of deceit could result in an F in the course, suspension or expulsion.  Any zero from cheating will not be dropped.  Finally, it must be understood that a student who knowingly aids in another student’s cheating or plagiarism... is as guilty as the other.

 

Assistance:   See me as much as needed.  I want to help you be successful in Engineering 130.  I encourage you to come during my office hours or to schedule other times for assistance.  You can drop by my office anytime, and if I am available I will help

 

Etiquette:  Please be on time.  Please turn off the audible alarm on pagers and telephones.  If you expect that you need to respond to a call, please let me know and please sit near an exit so you can leave and not disturb the class.  Violators will be asked to leave the class.

 

Lab Reports:  Lab reports are due one week after each experiment is completed at the beginning of the experiment.  Lab reports turned in during the lab period after lab starts will have a 10% deduction, and reports up to 24 hours late will have a 20% deduction.  After 24 hours a late report will not be accepted.  In addition to the written report an electronic copy attached as a file to email will also be submitted with the same due date.  The attached file should have the given filename’s listed in bold in the lab schedule, followed by your last name.  The report should either be in a rich text format (rtf file type) or a MS Word format (doc file type).  For example, if I turned in the crystal experiment it would have a filename of xtal_daniel.doc. 

 

MAKEUPS: There will be no makeup quizzes or exams (except under unusual circumstances).  Please let me know ahead of time if you will be absent if you wish to not receive a zero for an assignment.  If you are excused from missing a test, then the final will count 250 points instead of the 150 listed above.
