PLTW IED FINAL EXAM SCRIPT 2026
VERIFIED QUESTIONS WITH SOLUTIONS
GRADED A+
⩥ Tangent
Answer: A straight or curved line that intersects a circle or arc at one
point only.
⩥ Circumscribe
Answer: A triangle located round a polygon such as a circle. To draw a
figure around another, touching it at points but not cutting it
⩥ Principal Axes
Answer: The lines of intersection created from three mutually
perpendicular planes, with the three planes' point of intersection at the
centroid of the part.
⩥ Density
Answer: The measure of mass density is a measure of mass per volume.
⩥ Volume
Answer: The amount of three-dimensional space occupied by an object
or enclosed within a container
,⩥ Inscirbe
Answer: To draw a figure within another so that their boundaries touch
but do not intersect.
⩥ Obtuse Triangle
Answer: A triangle with one angle that is greater than 90 degrees.
⩥ Fillet
Answer: A curve formed at the interior intersection between two or more
surfaces.
⩥ Right Triangle
Answer: A triangle that has a 90 degree angle.
⩥ How is a geometric constraint different from a numeric constraint in
the inventor program?
Answer: Geometric constraint "bonds" two geometric parts (surfaces,
edges, centers) together (i.e., mate, flush). A numeric constraint is a
measurement or distance and constrains an object to be a certain length.
⩥ What advantages do CAD sketches have over freehand sketches?
Answer: It is usually faster to produce and more accurate. Can be looked
at in 3 dimensions and seen at different angles
, ⩥ What 3D CAD functions could be used to create a wire paper clip?
Answer: Spline
⩥ What feature would be used to create a 3D representation of a baseball
or softball bat that was created on a wood lathe?
Answer: Revolve
⩥ What do you need to know in order to perform a physical property
analysis?
Answer: What material it is made of and dimensions of the object.
⩥ Why is it important to perform a physical property analysis prior to
producing a part?
Answer: In order to find the weight and density
⩥ Why is it important to understand the mathematics used in physical
property analysis?
Answer: The Mathematics is important for you to determine the volume,
density, mass, weight and size of the object you are developming.
⩥ A work point is an independent entity whose location is defined in
Answer: Space
