Which elements are stresses, strains, heat distribution, and tolerances?

• A. Factors tested during CAD design
• B. Material properties
• C. Manufacturing constraints
• D. Cost factors

Answer: (A)

In CAD design you simulate how a part behaves under real conditions—how it carries loads, how heat moves through it, and you also check that its dimensions stay within required limits. Stresses and strains come from the mechanical analysis, heat distribution from the thermal analysis, and tolerances are verified to ensure the part will fit and function in the real assembly. So these elements are exactly the kinds of factors tested during CAD design. The other options describe different areas: material properties are intrinsic to the material itself, manufacturing constraints focus on how to produce the part, and cost factors relate to budgeting and economics rather than performance analysis.
