1 of 2 Individual Assignment 2: Modeling and Engineering Principles ...

Individual Assignment 2: Modeling and Engineering Principles Due: December 2, 2013 (submit online prior to the start of class on Monday) Maximum of 2 pages including references (see formatting guidelines below) and 1 page for appendixes. An optimal design process is based on the identification and application of engineering principles to the solution of specific needs. Engineering modeling evaluates the design constrains and specification to be satisfied by a new design. Engineering principles are the ideas, rules, or concepts that need to be kept in mind when solving an engineering problem. There is no one specific list of engineering principles that can be written down, because the concepts used to solve a problem will often be different depending on the type of problem encountered. As engineers you must be aware of the principles and features of your design. Address each of the points outlined below, as they relate to your specific design, in the order presented: 1. Identify two research publications related to your specific design that applies analytical or computer modeling based on engineering principles. (4) 2. How this publication related to the solution that you are designing? (4) 3. Which of the quantitative aspects of the modeling presented in the publication are more relevant to your problem? (4) 4. Can you adapt this model to the evaluation of your solution? (4) 5. Include the abstract of the publications as appendix to your HW (max 1 extra page). (4) Models are useful to develop and evaluate your ideas. A model will allow you to organize data, your thoughts, describe relationships, and analyze your proposed designs. As you may be confronted with a design problem that you are unfamiliar, either because the problem has never been solved before by anyone or (at the very least) it has never been solved by you. A model can help you recognize what you know and what you do not know about a problem and its solution. They can help you transform a new unfamiliar problem into a set of recognizable sub-problems that may be much easier to solve. Model building and testing is a skill to be mastered by all engineers. Importance of modeling: Proposed designs usually can not (and should not) be built and tested to determine their practical value (every potentially satisfactory design cannot be built due to financial and time constraints). Prototypes often do not work properly when first constructed; they require additional refinement and revision (more investment of both time and money). Some designs are hazardous to testers or to the environment (all risk should be minimized). 6. Identify what types of model you can apply to your design problem and solution, explain the reason for selecting model types (For example, if the design is to be an innovative manufactured product, an abstract model followed by a concrete mock-up of the system 1 of 2

might be preferable), and how will you apply them (other type of models no listed bellow can also be used)? Types of Models: – Iconic (visually equivalent but incomplete) o graphical (CAD, solid models) – Analogical models (represent function – functionally equivalent) o Physical models – prototypes o Qualitative models (glass fails at the surface under tension) o Process diagrams (circuits, chemical …) o Digital computer models?? – Symbolic o Mathematical models (sets of equations that can be used to describe and predict the behavior of systems, such as Hooke's law , Bernoulli’s equation, …) 7. What is to be gained from the model? Be explicit: Identify the specific result that the model is expected to provide. 8. Will your model predict some system variable as a function of time, provide a description of an object with sufficient detail for it to be manufactured, or prescribe a process that should be followed in order to achieve a particular goal in your solution?
