Section 1: Engineering Design Process & Problem-Solving Methodology (Q1-10)
Q1. In the engineering design process, which phase immediately follows the
brainstorming of alternative solutions?
A. Prototype construction
B. Analysis and selection of the best alternative
C. Final product testing
D. Public communication and marketing
B. Analysis and selection of the best alternative [CORRECT]
Rationale: The standard design process sequence is define → research → specify →
brainstorm → analyze → select → prototype → test → iterate; analysis and selection
logically follow idea generation to evaluate feasibility against constraints.
Correct Answer: B
Q2. A design team must minimize carbon emissions and ensure the product can be
recycled at end-of-life. These requirements represent which type of constraint?
A. Economic constraints
B. Manufacturability constraints
C. Sustainability and environmental constraints
D. Aesthetic constraints
C. Sustainability and environmental constraints [CORRECT]
Rationale: Carbon footprint and recyclability are environmental/sustainability
constraints; economic constraints address cost, manufacturability addresses
production feasibility, and aesthetics address appearance.
Correct Answer: C
Q3. The Preliminary Design Review (PDR) is conducted at which stage of the design
process?
,A. After market launch
B. After concept selection but before detailed design and prototyping
C. During the initial problem definition
D. After final manufacturing has begun
B. After concept selection but before detailed design and prototyping [CORRECT]
Rationale: The PDR evaluates selected concepts against requirements to approve
progression to detailed design; it occurs after down-selection but before committing
significant resources to prototyping and testing.
Correct Answer: B
Q4. The Critical Design Review (CDR) primarily evaluates whether:
A. The marketing strategy is effective
B. The detailed design is complete and ready for manufacturing
C. The project budget was underspent
D. The competitors have been eliminated
B. The detailed design is complete and ready for manufacturing [CORRECT]
Rationale: The CDR is a milestone gate that verifies all design specifications, analyses,
and documentation are complete and the design is frozen for production; it does not
address marketing or budget surplus.
Correct Answer: B
Q5. In engineering design, the term "iteration" refers to:
A. Performing each phase exactly once in sequence
B. Repeating design phases to refine and improve the solution based on testing
feedback
C. Eliminating the need for prototypes
D. Skipping the research phase to save time
B. Repeating design phases to refine and improve the solution based on testing
feedback [CORRECT]
Rationale: Iteration is the cyclical refinement of designs using test data to improve
performance, reliability, and manufacturability; successful designs rarely achieve final
form without multiple iterative cycles.
Correct Answer: B
, Q6. A project must stay under $50,000, use off-the-shelf components, and comply
with OSHA safety standards. These limitations are best described as:
A. Design variables
B. Design constraints and criteria
C. Engineering assumptions
D. Physical constants
B. Design constraints and criteria [CORRECT]
Rationale: Constraints are bounded limitations (budget, available components,
regulations) that the design must satisfy; they differ from variables which are
adjustable and assumptions which are provisional.
Correct Answer: B
Q7. During a brainstorming session for design alternatives, which rule should NOT be
followed?
A. Defer judgment until all ideas are generated
B. Encourage wild and creative ideas
C. Critique and eliminate ideas immediately to save time
D. Build on and combine the ideas of others
C. Critique and eliminate ideas immediately to save time [CORRECT]
Rationale: Immediate criticism inhibits creative thinking; effective brainstorming
requires deferring judgment to maximize idea generation, followed by separate
analysis and selection phases.
Correct Answer: C
Q8. The primary purpose of building a prototype in the design process is to:
A. Replace the need for mathematical analysis
B. Test and evaluate the design before committing to full-scale production
C. Serve as the final product for mass distribution
D. Avoid writing technical specifications
B. Test and evaluate the design before committing to full-scale production
[CORRECT]
Rationale: Prototypes allow physical testing, failure identification, and design
validation with reduced economic risk; they supplement rather than replace analysis
