Wind Turbine Experiment
Students working in teams of 6
will perform a wind turbine experiment. Each group will acquire one set of
data, and each group will submit a single lab report. Experiments will run in
Gym 1 of Carpenter
Sports Building. Click here for
the temporary entrance during construction.
Each lab group will turn in a
single report for each experiment. Reports must be typed. Reports should be
concise but complete. Use your own words; verbatim copying of the handout
should be avoided. Do not pad the length of the report unnecessarily.
The report must contain the following
- Title page
- Title of experiment
- Section number; Team ID; Names of group
- Date experiment was performed
- Date report was submitted
- Theoretical background
- What principle is this experiment
designed to illustrate?
- Describe the theory and any relevant
- Describe all components used during the
- Include a neat schematic diagram and/or
photograph with all parts
labeled and dimensioned (as required). Copying sections of a report, or
sharing sketches with other groups is not permitted.
- Provide a definition of all symbols
For each objective in a given experiment:
- Initial setup
- Parameters varied
- Raw data should be arranged in tabular
form. Some data may be tabulated in the Appendix.
- A completely worked-out sample
calculation is required for repetitive calculations.
- Use MS Excel (or any other spreadsheet
program) for tabulation and plotting graphs.
- Error analysis
- What factors contributed to uncertainty
in your results?
- Perform an analysis to show how all the
individual errors in your measurement contribute to the total error in
the final quantity.
- Suggest ways to reduce error in the
- Discussion and conclusions
- What did you learn from this
- What discrepancies did you notice
between theory and experiment?
- What would you do to improve it?
Include copies of all notes taken during the experiment: (1) Name of data
recorder, (2) group members present, (3) date, (4) all data recorded,
including brief comments to help you later during data reduction and
analysis. Do not use erasers during note-taking (just draw a line through
your mistake and proceed).
Grading of Reports
Fulfilling basic requirements
listed above (neatness and professionalism is key) will fetch the group an
automatic 6 points on a scale of 10. The remaining points will be awarded on
the basis of merit including the organization of thoughts, illuminating
discussion, and excellence of error analysis.
Lab reports are due no later than one week
after performing the experiment. Late reports will be penalized, 0.5 points for
every late day. Lab attendance is absolutely necessary. 5 points are
automatically deducted from your individual grade if you miss a lab session.
Evaluation Form may be used to allow students to rank their own
contribution, and that of their fellow team members, to the overall lab effort
and the resulting lab report. Each individual's ranking is averaged, assigned a
numerical value, and used as a multiplier on the team grade, to extract an
individual grade. This mechanism will be used to differentiate and
appropriately reward individual efforts. (You may be interested to know that
companies often use such peer evaluations to calculate annual raises.)
