ENTC 361 Exam 1 question & answers graded A+ 2023

ENTC 361 Exam 1 Pro-E Feature Based - correct answer Creates parts and assemblies by defining features(extrusions, sweeps, holes) Pro-E Parametric - correct answer The physical shape of the part of assembly is driven by the values/dimensions assigned to the attributes of it's features. It is possible to define a model at any time. Pro-E Solid Modeling - correct answer The computer model you create is able to contain all the information that a real solid object would have(volume, density, mass, inertia) Focused Analytical - correct answer Stress analysis, injections molding simulation of part. Quick feasiblity info, quick design changes. Comprehensive Analytical - correct answer High fidelity CAD models and dynamic situations. Allow quick multiple scenarios tested Quick feedback from design changes. Very Labor intensive Focused Physical - correct answer Foam core, rapid prototyping, machining. Physical part can be tested or evaluated. Lead time can be an issue, not real parts or materials. Comprehensive Physical - correct answer RP shells with prototype inners, real products. Gives you real feedback on how product will behave. Expensive. Usually done when it's too late to make changes. Intution - correct answer Going on someone's gut feel Pros: very quick and easy Cons: no documentation, little buy-in for item Multi-Voting - correct answer People vote on concepts Pros: Straight forward, quantitative, democratic Cons: not all opnions created equal, little connection to customer. Brainstorming - correct answer People discuss positives and negatives of each concept. Pros: More info that multivoting and intution, allows for some type of hybridization, documented. Cons: Still somewhat subjective Prototype and Test - correct answer Actual working prototype is built and tested. Data collected and best performing prototype is chosen. Pros: Most info possible, quantitative, allows for hybridization, Cons: Very expensive, very time consuming Decisions Matrices - correct answer Concepts are evaluated based on customer input or functional requirements. Pros: Documented, quantitiative, allows for hybridization, related to what customer wants. Cons: Can be very time consuming, Slot Modularity - correct answer Interfaces are different, non-interchangeable Very product specific. Ex. Driver airbag for a specific vehicle Bus Modularity - correct answer Common bus with same interface Ex. USB or bluetooth Sectional Modularity - correct answer Physical elements attach to each other with universal interface. very interchangeable parts, can be integrated with other components in more than one way.
