MAE 1351 Exam 1 Review (All correctly solved)

In the ___________ Stage the design engineer must address questions and answers from the customer's/client's perspective and from the engineer's perspective correct answers Problem Identification When a product is designed, one of the design considerations is how long will it be used before it is no longer effective, which is called correct answers life cycle environmental concerns are considered throughout the process, not just at the end, because an engineer's choices in the problem definition stage often influence the overall environmental impact and life cycle of the product correct answers green engineering Concept generation is correct answers the most creative phase of the design process A common technique for selecting the final concept is... correct answers a weighted decision table a useful document for evaluating and presenting the static mechanical conditions of the design correct answers mass properties analysis Engineers can have the shop people build a ____ model, a _____ model, or a ______ model correct answers Scale Model True Sized Model Mock-up concept can take data from a 3-D solid model and cut the pattern using computer numerical control (CNC) machines correct answers CAM systems For civil engineering projects, because no prototypes have been built, design modifications are common in the production stage. Contractors may find, for example, that ductwork does not fit within the space provided on the drawings, or they may find that piping needs to be rerouted around an obstruction. For this reason, in civil engineering projects, it is important to continue to document the design by making notations on the drawings where changes are made. These drawings are called correct answers as-built drawings concurrent engineering is sometimes referred to as ..... correct answers design for manufacturability. With concurrent engineering, designers, analysts, and manufacturing engineers work together from correct answers the initial stages of the design process. In this way, each person can apply his own expertise to the problem at hand from the start Using the principles of concurrent engineering, manufacturers can save correct answers thousands, even millions, of dollars.
