Project Due in RC 209 by 5:00 PM

 

 

Homework:  Unless otherwise noted, homework is due on the dates indicated above.  No late homework will be accepted without prior instructor approval.

Online Course Reserves:  Solutions to all homework and exam problems will be posted online on my webpage (www.cs.wright.edu/~pravi/Teaching).

 Design Project:  An individual design project will be assigned midway through the quarter, and accounts for 1/3 of the total homework grade (5% of the total course grade).  The design project is a MANDATORY component of this course, and its completion is required for a passing course grade.

 Lab Policy:  Completion of ALL laboratory assignments is required for a passing course grade.  Each assignment will require the submission of a typed report containing the following sections:

 Abstract (20 pts):  One paragraph summarizing the objective, approach, results and conclusions.

Objective (10 pts):  One paragraph briefly outlining the laboratory assignment and objectives.

Relevant Theory and Equations (20 pts):  Summary of all relevant theory and equations, as well as any preliminary calculations required for the assignment.

Experimental Procedure (20 pts): Detailed description of experimental procedures and equipment used.

Results and Discussion (20 pts):  Clear presentation and discussion of all requested results.  Results should be interpreted in the context of the relevant theory and equations, and comparisons between predicted and measured results should be made when applicable.

Conclusions (10 pts):  Brief summary of what was accomplished, including the extent to which the desired results were achieved, as well as lessons learned from the assignment.

 With the exception of the last laboratory assignment, all lab reports are due at the beginning of the next regularly scheduled lab meeting.   The last lab report will cover Beam Bending Parts I and II, and is due the last day of class.  Late reports will be accepted with a penalty of 20%.

 Exam Policy: The only materials permitted for the Pre-Req Quiz and each midterm exam are a calculator and ONE SIDE of an 8.5”x11” HANDWRITTEN crib sheet, which must be turned in with the exam.  A total of three (3) 8.5"x11" handwritten crib sheets will be permitted for the Final Exam.

 Grading:  Homework 15%, Pre-Req Quiz 5%, Exam I 20%, Exam II 20%, Final 20%, Lab 20%

 Grading Scale:  A course average within each of the following ranges will guarantee you at least the corresponding letter grade:  A: 90-100, B: 80-90, C: 70-80, D: 60-70, F: <60.
