Assignment 3c: Due Date: Friday 29th May 2015, 4:00 pm Please submit through online link at Learning @ Griffith

Weighting: 5% of the total marks for this course Submit a two-page laboratory report that addresses the following task:

Assignment Task

Design and implement an experiment to verify the relationship between the precession angular

velocity, the spin angular velocity (number of radians per second the gyroscope is rotating about the

z-axis in Fig. 1), the applied moment ( WrG × in Fig. 1) and the rotational mass moment of inertia (

zI ) of a gyroscope in steady precession.

∑ Ω= zyzx IM ω (1)

ωz – Spin angular velocity (rad⋅s -1

)

Ωy – precession angular velocity (rad⋅s -1

)

You are required to submit an individual laboratory report (2 pages in length) that describes clearly

and concisely the experiment done and results obtained. The report should be produced with a word

processor such as Microsoft Word and not hand-written. The report must contain a graph showing

verification of Eq. (1). Although laboratory work will be done in groups, each student must submit

their own individual laboratory report. It is expected the report will contain the following

components/sections:

Procedure:

This section should give the step-by-step procedure used to carry out the experiment.

Results and Discussion:

Results should be presented as a graph. The graph should be labelled underneath as Fig. 1. On the

graph, use lines to represent theoretical estimations and points to represent experimental data. Refer

to the figure in the discussion. The discussion will explain (in words) how the graph confirms the

relationship between the precession time period and the spin angular velocity. It also should offer a

brief explanation for any differences between the theory and the experimental results.

Conclusion(s):

Briefly state how the experiment fulfilled the specified aim and what was learned from the

experiment.

Marking Criteria

You will be marked based on the clarity of your experimental procedure, clarity and appropriateness

of your graph, clarity of presentation, accuracy of your reporting, correct use of English,

completeness, understanding of the experiment, inclusion of units, and for following the above

instructions.
