IET 226 MIDTERM EXAM REVIEW QUESTIONS AND ANSWERS
1. What's the difference between Raster Graphics and Vector Graphics? - CORRECT ANSWER✅✅Raster
Graphics are resolution based graphics. Whereas Vector Graphics are based on mathematical formulas
defining geometric primitive. Pixelization
2. What's the benefits of employing CAD system in Mechanical Design Perspective? - CORRECT
ANSWER✅✅Computer assisted systems, increase productivity of the designer, improve quality of
design, improve communication through more efficient documentation and provide a multi-purpose
data base.
3. Which other system can take benefits of geometry created by CAD system? - CORRECT
ANSWER✅✅CAM (Computer Aided Manufacturing), FEA,FEM (Finite Element Analysis; Finite Element
Method), CFD (Computation Fluid Dynamics), and Kinematics (Motion Analysis).
4. Three major Tasks of 3D CAD Design - CORRECT ANSWER✅✅Part Modeling (Sketch Mode, Feature
Creation, and Part Editing), Assembly Modeling (DOF-Degree of Freedom, Assembly Constrain, and CAD
Library), and Drafting(Detail Part Drawing, GD&T, Assembly Drawing)
5. What is CAM and what is major purpose of CAM? - CORRECT ANSWER✅✅CAM (Computer Aided
Manufacturing) to make connection between machining and CAD
6. What is FEA/FEM? What types of solution does it provided? - CORRECT ANSWER✅✅FEA,FEM (Finite
Element Analysis/Method) provides structural analysis vibration analysis, fatigue analysis, and thermal
analysis.
7. What is CFD? List examples of problem solved by CFD? - CORRECT ANSWER✅✅CFD (Computation
Fluid Dynamics) is the analysis of the fluid and thermal flow. Ex. The flow of hot water through pipes.
8. What are the three major interests of Motion Analysis (Kinematics)? - CORRECT
ANSWER✅✅Kinematics (Motion Analysis) is motion analysis of path, speed, and acceleration. As well as
Mechanism analysis.
