Assignment Brief

Background

Energy is a fundamental concept in the studies of the physical sciences (and, as a consequence, of the engineering practices). Although difficult to formulate in words, energy is deeply rooted in the studies of Dynamics as the quantification of the potential for motion associated with a force (or a system of forces). There are countless examples illustrating how energy changes from one form into another, yet obeying a basic principle, which establishes equivalence between the forms. In other words, energy is not created nor lost, but conserved. The proposed experiment provides means for illustrating the principle of conservation of energy and how phenomena pertaining to physical sciences can be modelled with this principle.

Requirement

1. Plot the “force versus extension” curve for a spring extended under the effect of hanging weights. The figure must include a title and the axes must be properly labelled.

2. From your data determine:

a) The spring constant.

b) Determine the energy stored in the spring, as it is deformed.

c) Calculate the potential energy associated with the “weight drop” procedure.

d) Compare the results for the elastic potential energy with the ones for the gravitational potential energy.

e) Elaborate an analysis of the experiment under the principle of conservation of energy.

3. Following the instructions for carrying out your experiment, answer the following question: upon dropping the weight and letting it hit the table, the weight hanger bounces back upwards, but does not hit the table a second time. Why?

Guidance notes and considerations

1. Suggested form for reports:

a. Cover: A special cover page should be provided for each laboratory report. It should show the course code, experiment title, and student ID.

b. The report should also include table of content, list of figures and tables with page numbers.

c. Summary/Abstract: This should contain the summary of all your work highlighting the aims and outcome of experimental findings and results. It provides, in brief sentences, an overview of the whole document.

d. Introduction: Give a statement of the Objectives of the lab experiment, its industrial application and benefits to engineering and design.

e. Theory: This section will need more information than is available in the laboratory hand-out. Entire background theory should be explained here; all equations and sample calculations should be accurately detailed here. Always use SI units and include them in each equation. Be sure to attain yourself to the relevant topics associated with your practice, though.

f. Equipment and Procedure: Report on the material used, kind of testing apparatus, and principal features of the test. Each report should be structured so that the reader will understand how the experiment was performed, what the results are, and what they mean. This will often require you to restate or repeat certain information which appeared in the laboratory hand-out. However, you should provide an account of the procedures for setting up and carrying the experiment, for data analysis, data collection and data representation, and not simply insert the instructions for operating the kit (or devices) deployed in your experiment.

g. Experimental Results: The main purpose of the Results section is to report and analyse data from the lab. State the principal findings and refer to tables or diagrams (if any) where details may be found. Sometimes the best way to show experimental results is with a figure which contains a plot of the data. Include a suitable chart title. Make sure to label the horizontal and vertical axis and identity the units. Identify and label all critical points

h. Discussion: Compare your results with those given in lecture or other references. Give reasons for discrepancies if serious differences appear to exist. Compare the different forms of energy associated with the experiment, experimental procedures, machine parts, etc. Comment on the theoretical principles guiding the practice. Mention possible limitations of the experiment/resources.

i. Conclusion and Recommendation: Summarise the key findings of your practice. Be concise, effective and attain yourself to the results of your experiment. Provide recommendations, if associated to your findings or stemming from them.

j. Appendix: Schematic sketches (or photos) of special apparatus and tables can be put in an appendix if you wish. This is also a good place for sample calculations. In general, do not include all computations, merely one complete set. Always include the data sheets you used to collect data during the laboratory session. It is recommended that you make a copy or PDF of the data sheets before handing in the original data sheet with the report.

Note: A report template that will serve as guidance will be made available on Moodle.

MOODLE UPLOAD INSTRUCTIONS

1. MAX 20 MB FILE SIZE Each assignment file should be uploaded to Moodle WELL before the submission deadline time.

2. IF MOODLE IS NOT WORKING If Moodle is not working or you have difficulties uploading your files, please try again later as Moodle should become operational again within 24-48 hours. You can email the teachers if you experience Moodle problems – but just please upload your files to Moodle in the normal way when it becomes operational again-before deadline. You are allowed to resubmit your assignment until final deadline.

3. NON-SUBMISSIONS Non-submissions will be deemed absent (AB), will receive a “0” mark, but this will not prevent your entitlement to a free resit at the next assessment opportunity, with the module mark being capped at 40% maximum.

SUBMISSION INSTRUCTIONS:

1. BACK UP You are strongly advised to keep your own personal back up copies of all files in a separate and safe location in case of loss.

2. STRUCTURE & LAYOUT Written report should have a logical structure, be page numbered, contain a contents page (indexed to page numbers), a conclusion and a reference list. It should be checked for accurate English grammar, spelling and punctuation.

3. VIRUS CHECK Please virus check your file prior to uploading to Moodle.

4. REFERENCES All material used in your report should be fully cited in your text and be fully listed in your reference list. If you read an original work by one author (primary reference e.g. Smith 2005) in another work (secondary reference e.g. Jones 2009), then both sources must be cited and acknowledged in your reference - for example: a. Smith (Jones 2009) states .……..OR b. Smith's study in 2005 (cited in Jones 2009) states .…….…..OR c. Jones (2009), in reporting Smith's 2005 study, states .…..…...

5. HARVARD REFERENCING Your reference list should be correctly presented using the CU Harvard (alphabetical) system of referencing. Accuracy and full correct presentation of references is important – please see the CU guidelines on Moodle.

6. ASSIGNMENT ASSISTANCE Assignment assistance and guidance will be provided by relevant tutor. You can also email your tutor to request for further support if the need arise.

7. Turnitin SUBMISSION and avoiding plagiarism: Submit your individual report via the Moodle Turnitin submission link. Coventry University College are very strict on plagiarism, so for your own sake you must ensure that your submission is entirely your own work. cite ALL references and DO NOT COPY OR PLAGIARISE ANY OTHER STUDENTS WORK OR AUTHORS WORDS OR FROM THE INTERNET. You are advised to submit a DRAFT copy of your submission to TURNITIN in order to check and avoid submitting any sections which may contain “plagiarism” or “poor academic practice” or “collusion” (please refer to further “plagiarism avoidance” guidance below).

8. Plagiarism avoidance:

Recommended Referencing Practice - Citations and Quotations

In order to avoid submitting any sections which may contain “plagiarism” or “poor academic practice” or “collusion” it is important that students should adopt the following referencing practice:

CITATIONS: Include an in-text citation (author and year of publication) and give the correct reference at the end of the work for any sources used or referred to or paraphrased in the work but not directly quoted.

QUOTATIONS: Mark up any directly quoted text using “quotation marks” (this enables Turnitin to identify “quoted” sections), add an in-text reference (author, year of publication and page number) and include the correctly formatted reference at the end of the work; Examples of “plagiarism” or “poor academic practice” or “collusion”: a. Excessive and inappropriate use of quotations.

e.g. Where the assessment learning objectives require a student to explain an argument but the student simply copies an explanation from another source, correctly annotating the work as a quotation. b. Quoted sections that are not correctly annotated as quotations (using quotation marks, which will allow Turnitin to identify quoted sections), but where there is an attempt to cite and reference the source. e.g. If a student includes separate paragraphs in the format “In 2005 Smith found evidence that…” and then copies the rest of the paragraph directly from the cited source.

c. Copying material from another source without indicating it is a quotation (indicated by using quotation marks, which will allow Turnitin to identify quoted sections). d. Omitting from the reference list and/or bibliography at the end of a submission any sources that a student has used to help formulate their own answer, even if the actual submission is written in the student’s own words. e. The use of substantial sections of text that have been previously written by others, but with no clear indication that the text is not the student’s own work. f. Copied sections of text from elsewhere without the source and extent of the copied section being clearly indicated in the text of the assignment.

g. Directly copied sections, such as several complete paragraphs, without in-text acknowledgement of the sources used.

h. Collusion e.g. two or more students with similar or identical work, or with large sections of work that are similar or identical in their individual submissions. This can apply to submissions from students studying at the same or different institutions regardless of the dates of submission. There is an exception to where students are legitimately working together on the same project.

*******DO NOT COPY ANOTHER STUDENTS WORK OR PLAGIARISE*******

FEEDBACK: FEEDBACK will be provided as follows: 1. Verbal Feedback on the quality of work submitted & improvement suggestions.

2. Written Structured Feedback via moodle detailing specific suggestions to help improve individual performance.
