• Explain the experimental results and their practical implications, [PO1, LO1] {C3}.
• Conduct each experiment correctly through established procedures and good record
keeping, [PO3, LO2] {P3}.
• Analyze the experimental data accordingly as required by each experiment, [PO4, LO3]
{C4}
• Produce a technical report for each experiment in a structured format and
professional manner. [PO8, LO6, SS4] {A3}

, ii. GENERAL LABORATORY INSTRUCTIONS
1. Must be prepared prior to the laboratory by reading the laboratory manual and
completing all assigned pre-laboratory work for the experiments before going to the
laboratory class. Students can visit the laboratory for study the types of equipment
and material to be used, before performing experiments.
2. Must come to the laboratory on time.
3. The posted safety rules in the laboratory must be strictly observed.
4. Attendance will be taken at the beginning of every laboratory session with
following the laboratory schedule published by the faculty.
5. Students will be formed into groups of two or three persons on the first laboratory
day. Once a student has signed up with a group, may not change groups without
prior approval of the lecturer.
6. Must actively participate in performing the experiments and do each laboratory
with an attitude of learning.
7. Students will perform the experiment in the group and turn in one report per
group with multiple discussion and conclusion with the contribution of each
member clearly identified in the report (i.e. analyze results together but each person
of the group will write their own discussion and conclusion). Use the provided
format when writing the report.
8. The raw data should be stamped and signed by the assistant engineer and the report
must be submitted to the assistant engineer.
9. The result table must be presented in tabular form and graphical work (e.g. graph)
can be drawn by hand or computer. Students are advised to bring blank and graph
papers to the laboratory, in which can do calculations and draw graphs.
understanding of business principles.1.4. Preparing for Business ExamsPreparing for business exams involves mastering both conceptual understanding
and practical application. Students are encouraged that may include constitutional law, criminal law, corporate law, human rights law, or intellectual
property law.2.2. Structure of Law ExamsLaw exams typically have a more structured format compared to business exams, often requiring students to
demonstrate knowledge of legal statutes, case law, and their ability t
10. Do not adjust the data to produce the “expected” results. If the results differ
significantly from reference values, check the setting carefully (wrong units, wrong
calculations, calibration, etc) and do the experiment again if needed. Draw your
conclusions based on these results. Try to explain any discrepancies.
11. All written laboratory reports are due approximately one week after completion of
the laboratory work (i.e. at the end of the week when the next laboratory is
performed). Late submission of laboratory reports (after the day on which the
laboratory exercise was performed) will have the final score reduced by 10% for
each week the report is late to a maximum of 50% reduction. The score will not
be given for each laboratory report is not submitted and for who did not attend
the laboratory work.
12. Laboratory reports must be hand written and your own work, if copying or
collusion is suspected, the final score will be reduced to a maximum of 30%
reduction.
13. For each section laboratory experiment, a peer and self-evaluation form must be
prepared by each team member and submitted to the assistant engineer
separately. The score of team member contribution will not be given for each
laboratory report who did not submit a peer and self-evaluation form.
14. The students who cannot come on their schedule (i.e must have M.C or permission
letter) can be replaced the experiment on another day. The students should be
informed the representative lecturer to arrange with the assistant engineer.
iii. REPORT WRITING
The following explanation has been prepared to guide the students for writing good
experimental laboratory reports in mechanical engineering laboratory courses. All reports in the
Mechanics and Materials Laboratory course (MEC 291) require a formal laboratory report. The
report should be written in such a way that anyone can duplicate the performed experiment and
find the same results as the originator. The reports should be handwritten (i.e. pencil will not be
