Name: ____________________________________________________________________ Pre-Test - Applying the Engineering/Design Process Answer Section TRUE/FALSE 1. ANS: F It would be difficult to start coming up with ideas to solve a problem when you haven’t figured out what the problem really is or what the restrictions to solving the problem might be. PTS: 1 2. ANS: T Although there are many versions of the Engineering/Design Process, all successful engineering requires the implementation of a systematic method for documenting the solution to a problem solving technique. Problem-solving is a tool, a skill and a process. As a tool problem-solving helps you solve a problem or achieve a goal. As a skill you can use it repeatedly throughout your life and as a process it involves a number of steps to achieve a successful result. PTS: 1 3. ANS: F Since there are several versions of the engineering/design process, there are no required number of steps in a successful process. Our course uses the process that incorporates 10 steps. However, some engineers roll multiple steps into one in order to simplify their process. PTS: 1 4. ANS: T Study models can be virtual objects designed using CAD. Study models can also be built using materials like cardboard, wood or Styrofoam. Many companies market modeling kits with snap-together or bolt-together parts that can be used to fabricate models of solutions to a problem. Models can be to scale or full-size. Prototypes are typically working models that can be full size or scaled down. This phase is used to determine problems with spatial relationships or component interaction. PTS: 1 5. ANS: F During the Test and Refine step, engineers examine and evaluate the prototype insuring its performance meets the criteria and constraints. Identify problems with the prototype’s design and brainstorm possible solutions while implementing changes until the prototype solves the problem reliably. If the prototype fails, engineers will first return to the Test and Refine step to continue the process. Otherwise, it’s back to the drawing board and a return to the brainstorming step. PTS: 1 MULTIPLE CHOICE Name: ____________________________________________________________________ 6. ANS: D After the brainstorming step, engineers should have a bunch of possible solutions to the design problem. They will then evaluate the possibilities for each idea and determine the pros and cons of each proposal. Engineers will then prioritize the characteristics of each solution and then select the best available approach. PTS: 2 7. ANS: B During the Production step of the Engineering/Design Process manufacturers deliver: o Fully Functional and Reliable Solution o Updated and Complete Documentation PTS: 2 8. ANS: D Ideate means to come up with ideas or to conceive solutions. PTS: 2 9. ANS: A Size, extension, movement and constraints. PTS: 2 10. ANS: C In engineering ideas, approaches and prototypes don’t pay the bills. The problems engineers attempt to resolve are not truly solved until the item is manufactured and ready for sale. PTS: 2 MULTIPLE RESPONSE 11. ANS: B, C, D Once the problem has be identified and the design criteria and constraints understood, the brainstorming process begins. During this step, anyone can contribute an idea without fear of being criticized. All ideas will be written down for greater examination later. This is a chance to get all possible solutions out on the table. PTS: 2 12. ANS: B, C, E Deliverables fro the Documentation and Presentation step in the Design/Engineering Process should include the following: o Project Presentation o Gant Chart o Dimensioned CAD / CAM Design o Component Specifications o Detailed Design Notes Name: ____________________________________________________________________ o o Component Specifications Manufacturing / Assembly Instructions PTS: 2 13. ANS: B, D You must generate ideas before you can explore possibilities and then select an approach. PTS: 2 14. ANS: A, B, D, E Through design you can make more use of the time you have, be more efficient, and get more done with the least amount of waste in materials, manpower and money. PTS: 2 15. ANS: A, B, C, E It really doesn’t matter what you use as long as it helps you work out the problems. However, robotics modeling kits like Mindstorms, Vex and Tetrix are more likely used to create working models or prototypes of the solution. They are not normally considered to build study models.
