MECHANICAL ENGINEERING DESIGN
COMPREHENSIVE EXAMINATION TEST
COMPLETE QUESTIONS AND CORRECT
ANSWERS
●● life cycle
Answer: When a product is designed, one of the design considerations is
how long it will be used before it is no longer effective, which is called
life cycle.
●● green engineering
Answer: 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.
●● Concept generation
Answer: Concept generation is the most creative phase of the design
process.
●● weighted decision table
Answer: A common technique for selecting the final concept is a
weighted decision table.
,●● mass properties analysis
Answer: A useful document for evaluating and presenting the static
mechanical conditions of the design is mass properties analysis.
●● Scale Model
Answer: Engineers can have the shop people build a Scale Model, a True
Sized Model, or a Mock-up concept.
●● CAM systems
Answer: CAM systems can take data from a 3-D solid model and cut the
pattern using computer numerical control (CNC) machines.
●● as-built drawings
Answer: 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 as-built drawings.
●● design for manufacturability
Answer: Concurrent engineering is sometimes referred to as design for
manufacturability.
●● initial stages of the design process
, Answer: With concurrent engineering, designers, analysts, and
manufacturing engineers work together from the initial stages of the
design process.
●● thousands, even millions, of dollars
Answer: Using the principles of concurrent engineering, manufacturers
can save thousands, even millions, of dollars.
●● patents
Answer: Patents are a way to protect the intellectual property of a new
design.
●● Three oaths of a patent
Answer: The three oaths of a patent are: 1. A written document made up
of a specification (description and claims) and an oath or a declaration.
2. A patent drawing (Figure 5.14) in those cases in which a drawing is
necessary. 3. Filing, search, and examination fees.
●● Graphical communications
Answer: Graphical communications has supported engineering
throughout history.
●● smallest change in a design
