                                                                   Rubber Band Powered Car

A Freshman Engineering Design Project
Developed by P.K. Imbrie, Purdue University
(Developed while at Texas A&M University)

Report Requirements

Engineering Content Requests

From an engineering design standpoint, the report of the project should address the following areas:

  •  problem identification (an introduction to the problem),

  • preliminary ideas or concepts (copies of rough sketches should be included)

  • refinement of a design (scaled sketches of the final design are requested in the project statement), and

  •  analysis and implementation (results of the demonstration of prototypes).

 Experimentally obtain distance versus time data (as described below) and provide a plot of this information.

  • From the experimental data, estimate and plot the vehicle’s velocity versus time.

  • From the experimental data, estimate and plot the vehicle’s acceleration versus time.

  • Using the above graphs, determine an appropriate velocity function and analytically estimate the distance the vehicle traveled and compare this to the measured data.

  •  “Estimate” the amount of energy stored in your engine just prior to the release of the vehicle.  Compare this to your estimate of how much energy was actually delivered to the vehicle.

 Include a final description of your design that includes

  • a single prototype

  •  the results of the project

  • the functionality of the design

 At this point, the engineering professors are not interested in detailed design drawings, just good sketches of the final design and a report that documents the complete design process.  Analysis is limited to what is asked for in the project statement.

English Requirements

In contrast to the technical information contained within the report, we will look at the quality of your organization, development and writing.  From an English standpoint, the report should adhere to the following qualifications:

 Overall

  • is well-organized into logical, separate report sections.

  • uses a clear system of highlighted headings to identify report sections.

  • demonstrates an understanding of the Killingsworth, Chapter 9 reading (provided in class)

Content

  • begins with a clear introductory section·         thoroughly reviews the methods by which the product (the car) was developed.

  • documents the results of the test trials.

  • discusses (analyzes) the product’s (car’s) performance, indicating strengths and weaknesses and comparing expected results to actual results.

  • includes any conclusions or implications drawn from the work.

Writing Style

  •  uses clear sentences with active wording, only using the objective style when appropriate.

  •  uses well-structured paragraphs.

  •  is consistent in style (doesn’t sound like it was written by four different authors).

  •  uses general audience terms where possible and appropriate (no unnecessarily complex writing). 

  •  avoids errors in grammar, spelling and punctuation.

 Graphics

  • are titled and labeled.

  • are referenced in the text and explained as needed.

A clear understanding of this project-report process will benefit you in the future.  This presentation is similar to future projects but contains less detail.  Such work is commonplace in the professional world.
