EMS410U- Experimental Design and Practice 1

Coursework Information Sheet

CW 2 (50%) Beam Deflection Report

Issue date: 11th  November 2025

Submission: Online submission via QMplus; see formatting details below

Due date: 2 weeks after the lab (See QM+ for more details)

Note: This is an individual assessment

Your report should include the following sections:

1. Title Page: Follow the instructions on the QMplus submission point and lecture in Week 10.

2.   Introduction and Background Theory: Give the aims and objectives of the

experiment. You need to give all the main equations used to design your experiment and to analyse your data. Provide the key principles behind them, explaining where they come from and what assumptions they are based on (from the module lectures and lecture notes). E.g., when you calculate the maximum bending moment of the beam, you should also explain what a bending moment is.

You might want to write a rough Introduction section first, and come back and revise it when you have finished writing the rest of the report and are clearer what the experiment is about.

3. Apparatus: This section should include a clearly labelled 2-D schematic diagram of the apparatus.

NO PHOTOGRAPHS

NO 3-D SKETCHES

NO FREEBODY DIAGRAMS

It should also contain a description of the apparatus AND instrumentation, and not simply a list of the parts and equipment.

4. Testing Procedure: This should be an account of WHAT WAS DONE. It should therefore be written in the past tense and be impersonal.

E.g. “The position of supports around the loading mechanism was set” is correct,

“I positioned supports around the loading mechanism” is incorrect (not impersonal)

“Position the supports around the loading mechanism” is incorrect (instructional and not past tense)

It should NOT be written as a set of instructions or a Lab sheet. You are telling the reader what YOU did; NOT instructing them on what THEY should do.

The Procedure section should also include the design stage of the experiment (described in words), where you decided on the parameters of the experiment. In this Procedure section, refer, where appropriate, to the Introduction section of the report (for the equations used) and Results section of the report (for the values measured/calculated)

5.   Results: This should include all your Results; both quantities you measured in the lab and things you later calculated.

The results section should include a 1 full set of sample calculations. This includes the calculations you performed during the design stage of the experiment and the calculation of E for both configurations. Taking into account the reading errors, calculate the overall errors for both values of E. Sample calculations should refer to equations, where appropriate, to the Introduction section above.

DO NOT PUT RESULTS IN AN APPENDIX.

6.   Discussion: Your discussion should:

•    Comment on the agreement or otherwise between the two values of modulus of elasticity obtained from the experiment. Which value would you have the most confidence in and why?

•    Comment on both values of the overall error of the modulus of elasticity. What does it tell us about the accuracy of the instrumentation?

•    Compare your results with the value of the modulus of elasticity cited in the literature (assume the material is mild steel). What was the percentage of disagreement?

•    Comment on the validity of the experiments. Was the data “repeatable”, i.e. did the results of repeated experiments agree with each other?

•    Comment on the “accuracy” of the experiment. What are other possible sources of error/uncertainties in the experiment besides the accuracy of the instrumentation, and what did you do to minimize these? Can discrepancies in the results only be explained by the accuracy of the instrumentation or does it concern the overall validity of the experiment as discussed above?

7.   Reference List: There are various ways to reference your sources. For this report use the Numbering system (often referred to as “Vancouver” style). In this style the references are numbered in the order they are referred to in the text and then listed all together at the end of the report (not in footnotes on each page). The only thing that appears in the text is the reference number.

Example

In the text

The boiling temperature of water at 101.325 kPa is equal to 99.974 °C [1].

In the reference list

1.   The Engineering Toolbox, water thermophysical properties,

https://www.engineeringtoolbox.com/water-thermal-properties-d_162.html, accessed 3rd  Dec 2022

Note that internet sources are fine (NO Wikipedia please), but always give some indication of what the site actually is (in this case, The Engineering Toolbox). Don’t simply list the URL.

For internet sources, give the date you accessed it (sites constantly change), but for other sources, give the year of publication.

You can reference lecture notes from this or other modules, but DON’T reference the lab sheet.

Finally, this is a Reference List. Anything listed should be specifically referred to at least once in the text of the report. It’s not a Bibliography, which is a list of recommended further reading.
