PLTW IED FINAL CERTIFICATION
EVALUATION TEST 2026 FULL SOLUTION
GUIDE GRADED A+
⩥ Black Box Model.
Answer: How your inputs are translated into your outputs - will not
know how it works as a system until you perform the structural analysis
⩥ Parametric Modeling.
Answer: A CAD modeling method that uses parameters to define the
size and geometry of features and to create relationships between
features. Changing a parameter value updates all related features of the
model at once
⩥ Precision.
Answer: The ability to repeat the same dimension over again
⩥ Accuracy.
Answer: The degree of closeness to the accepted value
⩥ Bilateral Tolerance.
Answer: A limit on dimensions that ranges in both directions, both
below and above
, ⩥ Unilateral Tolerance.
Answer: A limit on dimensions that can only go in one direction
⩥ Maximum Material Condition (MMC).
Answer: Lower limit of internal feature i.e. hole(Smallest it can be: to
make sure the object fits fit and is not too large)
Upper limit of external feature i.e. peg (Largest it can be: to make the
object isn't too large)
⩥ Least Material Condition (LMC).
Answer: Upper limit of internal feature i.e. hole(largest it can be:
Control hole at largest size on object, so it isn't too close to the edge of
the object)
Lower limit of external feature i.e. peg (Smallest it can be: Make sure
the peg doesn't slip out too easily)
⩥ Engineering ethics.
Answer: The set of behavioral standards that all engineers are expected
to follow
NOT A BLUEPRINT, because blueprints are for physical objects.
⩥ Innovation.
