Into to Engr Exam 1
| Term | Definition |
|---|---|
| Engineering | Designers who make stuff and fix problems for people |
| What is ABET | the Accredited Board for Engineering and Technology. Governing body for universities |
| Technician | Can fix things, doesn't design them, only has to know how they work |
| Design | Deciding how something will look, work, function |
| What do modern engineers have to worry about? | Energy and the environment |
| Difference between engineering and engineering tech | Engineer: Higher level math, higher theory and more inventions Engineering tech: Less theory, more innovation than invention, and practical applications |
| Why do scientists do what they do? | KNOWLEDGE |
| Why do engineers do what they do? | To design things and solve problems for the people! |
| What is important about the engineering problem solving/design process? | It has iterations so it is possible to go back and fix things or come up with something else |
| How do roadmaps translate to design problems? | Gives learning engineers skill acquisition and prerequisite development |
| Design problem solving process | Identify the problem -> Gather data and information -> Find and state theories/formulas -> Make assumptions -> Solve the problem -> Verify results -> BEGINNING |
| What is systems engineering? | Overall picture of how something is designed and used (implemented) |
| Functional requirements | Measurable values that capture the desired physical or physics based preferences in a design (The car has 4 seats/ the car has 400 horsepower) |
| Non-functional requirements | Tested by presence alone (present or not present) and is not associated with measured performance (The car is red) |
| Is it possible to go from a non-functional to a function requirement | Yes. Ex The car is red -> The color of the car is made up of 251 red, 3 yellow, 4 green (Now the color is measurable) |
| Temperature conversions | K=C+273.15 F=9/5(C+32) C=5/9(F-32) |
| Mathematical models | Graphs, formulas, etc. that tell us how something is going to act |
| Designing vs Building | Designing is a more formal process of documenting, specifying, and figuring things out, while Building is the process of physically following the design and bringing the product into the tangible world |
| Design variable | Things designers can control |
| Behavior variable | A variable that is a function or response of a system of other measured values. Ex the volume of a box is a function of the length, width, and height |
| Parameters | Boundaries or specifications or known, unchanging entities like gravity on earth=9.81 m/s^2 |
| Objective functions | A mathematical formula that represents the specific goal you want to achieve that could be minimizing or maximizing |
| Inequality constraints | Mathematical limitations on a design that must be less than or equal to a desired measurements. Ex the engine shall weigh less than or equal to 2000 lb |
| Equality constraints | Mathematical limitations on a design that must equal a desired measurement. Ex the box must have 24 candy bars |
| Side constraints | Limitations on design variables in the decision space. Ex the length of the box shall be between 70 ft and 150 ft |
| What is a budget? | A plan created to coordinate expenses and resources |
| Technical budget | A budget used by engineers to achieve significant outcomes that relate to the success of engineering activities or projects |
| Stakeholder | Anyone who has involvement in a project and will get something out of it (customer, investor) |
| Plan for contingencies | Back up plan with budget alternative in case of a problem |
| Why should we have a plan for contingencies? | Increases resource diversity, provides a living record of design activity that tracks progress, and establishes KPIs that can be used to evaluate performance relative to stakeholder expectations |
| KPIs | Key performance indicators |
| Gantt chart | A visual and chronological representation of design activity progress |
| Professional Engineer | Take a state test to get the title of PE |
| Biggest engineering fields | Mechanical, civil, chemical, electrical engineering |
| What do you often need to be a civil engineer? | The title of professional engineer or PE |
| Optimization | Finding the best or most efficient solution, usually with some mathematical formula or model |
| Neat problem presentation steps | Problem statement, diagram, theory, assumptions, solution steps, identify results and verify accuracy, and discussion/ conclusion |
