MECHANICAL ENGINEERING DESIGN
EXAM SCRIPT UPDATED COMPLETE
QUESTIONS AND ANSWERS EXPERT
REVIEWED
●● Criterion
Answer: A performance GOAL the design should achieve (ex: must hold
500 lbs).
●● Constraint
Answer: A LIMIT the design must stay within (ex: must cost under $10).
●● Design brief
Answer: Document defining the problem, goals, constraints, and
background.
●● Abstract
Answer: Brief summary of a report's purpose and findings, appears at
the BEGINNING.
●● Appendix
Answer: Supplemental material (drawings, data, charts) grouped at the
END of a report.
, ●● Decision matrix
Answer: Weighted scoring tool to objectively compare design
alternatives.
●● Optimization
Answer: Making a system as effective as possible within its constraints.
●● Orthographic drawing
Answer: Front, top, and side views on a flat 2D sheet. Standard
engineering drawing.
●● Isometric drawing
Answer: 3D view with all axes at 30° equal angles. No vanishing points.
●● Perspective drawing
Answer: 3D view with vanishing points. Looks most realistic.
●● Oblique drawing
Answer: Front face drawn in true shape, depth lines drawn at an angle
(usually 45°).
●● Line graph
