PLTW - IED Final Exam UPDATED
ACTUAL Exam Questions and CORRECT
Answers
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.
