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;

10. 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.

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

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. If you are a person with a disability and
anticipate needing any type of accommodation in order to participate in this class, please advise
us and make appropriate arrangements with Disability Services (293-6700).
