AMME2500 Engineering Dynamics 2021:
Gyro Lab Report (5%)

General Information:

• This lab report is due Saturday 22nd May 11:59pm
• Late reports will be deducted 5% (5 marks out of a possible 100) for each
day late, starting from midnight on the day after the report is due and
including weekends. Reports that are 10 days late or more will receive
zero marks.
• Any special consideration requires you to go through the Special
Consideration process via Sydney Student.
• Any incidence of academic dishonesty or plagiarism will result in the
issue being followed up with the Academic Honesty Coordinator and then
onto the University Registrar, and will result in zero marks for this
assessment, and may result in automatic failure of this unit of study. For
more information on academic honesty, see:
https://sydney.edu.au/students/academic-dishonesty-and-
plagiarism.html
• This assignment should take the average student 4 hours to complete.

What you need to do:

• On Canvas, click on “Modules” and scroll down and click on “Gyroscope
Laboratory”. This page will contain information on the laboratory task.
• Watch the laboratory task video on Canvas that explains the background
theory, physical lab activity and experimental data and what you need to
complete for the report.
• Live remote lab demonstrations will be performed via Zoom during
Weeks 4-7: links will be available via the lab Canvas pages.
• Download a copy of the experimental datasets that have been pre-
generated: you will use these datasets when completing your report.
• You will need to develop a lab report on the laboratory activity that
includes information on the background to the experiment, the
experimental aims, method, results and discussion conclusion. The lab
report is an individual assessment task. The lab report is to be submitted
in the Canvas link under “Assignments” any time before Saturday 22nd
May 11:59pm
• If you have any questions about the lab task, please post a message to the
Canvas discussion forum for the gyro lab, or feel free to send an email to
the lab demonstrators, Mr. An Nhien Truong
(annhien.truong@sydney.edu.au) or Mr. Hoai Cuong Nguyen
(hoaicuong.nguyen@sydney.edu.au).


Report Instructions:

• General notes for the report:
o This is an individual assessment task
o The maximum length of the report is four pages, which excludes
the cover page, references and an appendices (these can be on
additional pages)
o Past tense is recommended to be used to describe the
experimental steps. In technical reports, Tables and Figures should
have titles, and “first person” and “second person” (e.g. I, we and
you) should not be used.
o Graphs and plots must be clearly titled, with correct use of axis
labels and legends, units must be specified
• Your report should include the following sections:
o Cover page: Include your full name and student ID
o Introduction and Aims:
State the main objectives of the experiment.
Include background information about gyroscopic motion.
o Method
Describe the test methodology and procedure.
Note that diagrams and photos of tests and apparatus (if
there are) are important to help readers to visualize the
experiment and be able to conduct a similar experiment.
You may annotate figures and images found on the Canvas
page/videos or draw your own figures.
o Results:
Include Tables and Figures to present the results.
Include calculation examples. Note that “excessive”
calculations and large data are recommended to put in
Appendices.
Test results section may include two sub-sections:
• Decay of flywheel angular velocity over time
• Precession angular velocity and moment of inertia
o Discussion:
Discuss the results of experiment 1 and reasons for the data
observed.
Compare the average experimental value
exp
with the
given theoretical value
the = 0.004 kg.2. Students do not
need to derive the theoretical value. Discuss the results.
The lab demonstrators observed that when L was positive,
the precession was clockwise (CW), but when L was
negative, the precession direction was opposite, i.e.
counter-clockwise (CCW). Explain why this is so (~50-100
words + diagram if needed). Hints: (1) the suggested reading
sources maybe helpful; (2) Think about vector cross-products
Reading sources suggested on the lab Canvas page may be
helpful for discussion.
o Conclusions:
Summarise key points of the experiment.
State main conclusions drawn from the obtained results.

o References:
Cited sources should be reliable and/or published. You may
refer to relevant sections of the course textbooks.
