PLTW - IED EOC Review Terms Exam With Accurate
Solution 2024-2025
Innovation An act of making a new improvement to an already existing technological
product, system, or means of doing something.
Invention A new product, system, or process which did not exist previously done
through study and experimentation.
Design Brief - A written plan that identifies a problem to be solved and that defines its
criteria and constraints. A design brief encourages thinking of all aspects of a problem
before attempting a solution.
Design Process-Answer A process for the systematic solution of problems, with criteria
and constraints, that results in the generation of many solutions to solve a problem or
meet a human need/want and narrowing those solutions down to one final choice.
Construction Line -Answer Thin lines used as guides while sketching/drawing.
Hidden Line - Answer A line type that represents an edge that is not directly visible,
because it is behind or beneath another surface.
Isometric Sketch - 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 - Answer Views of an object projected onto two or more
orthographic planes.
Object Line - Answer A heavy solid line used on a drawing to represent the outline of an
object.
, Oblique Sketch - 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 - 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 - Answer A type of pictorial drawing where vanishing points are
used to give the depth and distortion that would have been viewed with the human eye.
Perspective drawings can be drawn using one, two and three vanishing points.
Shading - Answer The way light and shade are shown on a drawing or map.
Technical Working Drawing - Answer A drawing that is used to show the material, size
and shape of a product for manufacturing purposes.
Tone - Answer The general effect of color or of light and shade in a picture.
ANSI - 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 Those lines that are thin lines capped with arrowheads, that could be
broken along its length to provide space for the dimension numerals.
Extension Lines - Solution Thin lines that identify the extent of a dimension. Extension
lines begin with a small break away from the object and extend to about .125 inches
beyond the latest dimension line. Extension lines may cross object lines, centerlines,
hidden lines and other extension lines but never cross dimension lines.
International Organization for Standardization (ISO) - Answer A non-governmental
global organization whose principal activity is the development of technical standards
through consensus.
