PLTW - IED Final Exam Questions And
Answers Rated A+ 2024.
Innovation - correct answer. An improvement of an existing technological product,
system, or method of doing something.
Invention - correct answer. A new product, system, or process that has never existed
before, created by study and experimentation.
Design Brief - correct answer. A written plan that identifies a problem to be solved, its
criteria, and its constraints. The design brief is used to encourage thinking of all aspects
of a problem before attempting a solution.
Design Process - correct answer. A systematic problem-solving strategy, with criteria
and constraints, used to develop many possible solutions to solve a problem or satisfy
human needs and wants and to winnow (narrow) down the possible solutions to one
final choice.
Construction Line - correct answer. Thin lines that serve as guides while sketching or
drawing.
Hidden Line - correct answer. A line type that represents an edge that is not directly
visible, because it is behind or beneath another surface.
Isometric Sketch - correct answer. A form of pictorial sketch in which all three drawing
axes form equal angles of 120 degrees with the plane of projection.
Multiview Drawings - correct answer. Views of an object projected onto two or more
orthographic planes.
Object Line - correct answer. A heavy solid line used on a drawing to represent the
outline of an object.
Oblique Sketch - correct answer. A type of sketch involving a combination of a flat,
orthographic front with depth lines receding at a selected angle, usually 45 degrees.
, Orthographic Projection - correct answer. A method of representing three-dimensional
objects on a plane having only length and breadth. Also referred to as Right Angle
Projection.
Perspective Sketch - correct answer. A form of pictorial sketch in which vanishing
points are used to provide the depth and distortion that is seen with the human eye.
Perspective drawings can be drawn using one, two, and three vanishing points.
Shading - correct answer. The representation of light and shade on a drawing or map.
Technical Working Drawing - correct answer. A drawing that is used to show the
material, size, and shape of a product for manufacturing purposes.
Tone - correct answer. The general effect of color or of light and shade in a picture.
ANSI - correct answer. American National Standards Institute: A private, non-profit
organization that coordinates the development and use of voluntary consensus
standards in the United States.
Dimension Lines - correct answer. Lines that are thin lines capped with arrowheads,
which may be broken along their length to provide space for the dimension numerals.
Extension Lines - correct answer. Thin lines used to establish the extent of a
dimension. Extension lines begin with a short space from the object and extend to about
.125 inches past the last dimension line. Extension lines may cross object lines, center
lines, hidden lines, and other extension lines, but may not cross dimension lines.
International Organization for Standardization (ISO) - correct answer. A non-
governmental global organization whose principal activity is the development of
technical standards through consensus.
Mean - correct answer. The average or central value of a set of quantities.
Median - correct answer. Referring to the middle term or mean of the middle two
terms of a series of values arranged in order of magnitude.
Mode - correct answer. The value that occurs most frequently in a given data set.
Numeric Constraint - correct answer. A number value, or algebraic equation that is
used to control the size or location of a geometric figure.
Annotate - correct answer. To add explanatory notes to.
Assembly Drawing - correct answer. A drawing that shows the various parts of an item
when assembled.
