MAE244 Dynamics and strength laboratory SALLABUS MAE 244 Syllabus 1. Course Goals: The purpose of this course is to experimentally examine concepts developed in static, dynamics and strength of materials courses. Students will have the opportunity to test theories proposed in these courses, check the validity of assumptions and explore limitations of the theory. They will also gain hands on experience with test equipment and develop their writing skills through the preparation of lab reports. 2. Course Description: Students will conduct basic experiments in dynamics and strength of materials, including mechanical properties and stress-train curves of materials under tension, shear and tension, shear and torsion, electrical resistance strain gages, stress concentrations through fringe pattern analysis, hardness, and fracture of metals, vibration of components. Students will learn modern instruments. Students are encouraged to use the “Pro E” software to draw three-dimensional components used in the experiments. 3. Course Outcomes: This course contributes to outcomes: (a) an ability to apply knowledge of mathematics, science, and engineering; (b) an ability to design and conduct experiments, as well as to analyze and interpret data; (e) an ability to identify, formulate, and solve engineering problems; (g) an ability to communicate effectively; (k) an ability to use the techniques, skills, modern instruments and software necessary for engineering practice; 4.

Course Requirements Attendance: Attendance and participation count for 10% of the course grade. Students are required to attend and participate in all labs. Participation points are lost in case of being late to class or failing to contribute to performing the experiment. Every effort should be made to inform the instructor or T.A. if a schedule conflict exists (in extreme circumstances), so that arrangements can be made to make up the lab during a different session. Please do not bring food or drinks to class. Prelab Quiz: Take home pre-lab quizzes are found at the end of this manual laboratory exercise. Pre-lab quizzes must be completed and turned in at the start of the lab session. No late pre-lab quizzes are accepted. Lab Reports: Mandatory: 10 point penalty for each day late (Maximum 30 points). Reports are due at the start of the next lab session. Lab report must be submitted by each student. According to the guidelines for writing a lab report in this manual, reports should be prepared using a word processor for text and graphics package for data plotting. The students are also encouraged to use Pro ENGINEERTM for the schematic representation of the lab test setup and the associated modeling analysis. Grading: For a 'normal' distribution, final grades will be based on an average of all lab scores and according to the following scale. 90 - 100 A 80 - 89 B 70 - 79 C 60 - 69 D 0 - 59 F Depending on the distribution, however, the grades may be 'curved'. An average grade is a C. The instructor reserves the right to raise a student’s grade by one letter depending on the student’s overall performance. Grading Policy of Laboratory Exercises Attendance: 10% Prelab Quizzes: 20% Short Lab Reports 70% ________ 100% Total The format outlined below will be required of the regular lab reports. Reports that do not follow the format will be returned without a grade. It should be noted that this format is very typical from many university lab report formats and is not too different from the 2 a.2 MAE244 Dynamics and strength laboratory SALLABUS a.3 format required for manuscripts in technical journals. Refer to "Guidelines for Writing a Lab Report" for specific directions. Format of the short lab reports will be explained in class. Report Grading: Cover Page and Introduction 10 pts Schematic of setup 5 pts Experimental Results 30 pts Discussion 10 pts References and Appendix (Data sheet must be enclosed) Neatness, arrangement, spelling completeness, Tables and Graphs (construction and appearance) Total 5 pts 10 pts 70 pts 11. Ethics: Each student must submit their own report. No photocopying except for lab data sheets. Students are encouraged to discuss lab reports with other students, but lab reports must be original and from one student. Reports that resemble another student’s report will be returned with a score of zero. Students are responsible for following the rules and guidelines for academic honesty and plagiarism that are specified in the Student Handbook. 12. Statement on Social Justice: WVU is committed to social justice. The instructor of this course concurs with WVU’s commitment and expects to maintain a positive learning environment based upon open communication and mutual respect and nondiscrimination. Our University does not discriminate on the basis of race, sex, age disability, veteran status, religion, sexual orientation, color, or national origin. Any suggestions as to how to further such a positive and open environment will be appreciated and given serious consideration.
