PLTW: IED SEM1 2015 FINAL REVIEW
Terms in this set (51)
The first step in creating a model using the CAD program is to:
In inventor, when you start a new sketch, which axes represent the sketch coordinate system?
X and Y
Creating sketch geometry is as easy as drawing a closed shape. What are some simple rules for successful sketching?
Keep the sketch simple,
Draw roughly to size and shape,
Accept default dimension
Lines, circles, arcs and rectangles are all examples of:
Two dimensional sketching tools
Elements of sketch can be adjusted by:
Grip editing (selecting and dragging)
The process of using lines, circles, arcs and rectangles to create the basic design element that defines the approximate size and shape for features in a part:
These are the rules that remove the degrees of freedom between two selected components, positioning them relative to one another:
Generating a large quantity of idea for a solution to a problem is called:
Engineers create _________________ to quickly record, communicate and investigate ideas.
The most common view used in three-view, multi-view drawings are ________________.
Front, top, right side
What term best describes the list of items below?
- Must be made out of 4 to 6 pieces
- Must be interlocking
- Part cannon extend more than three units in any direction
- No two parts can be the same
A full-scale working model used to test a design concept is called a(n):
An improvement to an existing technological product, system or method is referred to as a(n):
A(n) _________________ is the most common method of communicating the shape and size of an object that is intended for manufacture.
The basic dimension on a multi-view detail drawing that indicates indicates the distance from front to back:
Generally, which is the first view places or created in a multi-view drawing or sketch>
Never dimension a(n)...
The first part brought into an assembly is known as the base component. The base component should always be ____________.
A(n) ____________ is a person who is trained in and uses technological and scientific knowledge to solve practical problems.
The organization that sets standards for drawing symbols, line conventions and dimensioning practices is known as:
ANSI (American National Standards Institute)
If a designer/engineer needs to calculate how many quarts of paint are needed to double coat 500 of one particular part in an assembly, what physical property would they need to know?
37.28 in^3 is the answer to a physical property calculation. What physical property calculation does it represent?
How many degrees of freedom (DOF) remain on an ungrounded part after a single mate constraint has been applied?
What type of document includes the following section headings?
- Problem statement
- Design statement
d2*.5 is considered what type of constraint?
The Coordinate System that uses a distance and an angle to plot points is called:
1- Define a problem
2- Generate Concepts
3- Develop a solution
4- Construct and test a prototype
5- Evaluate solution
6- Present solution
The amount of space occupied by a substance or object or enclosed within a container:
The distance from the center point to the edge of a curved surface or circle.
The number of square units required to cover a surface.
Constant, non-commercial relationships between the parts of a geometric figure. Examples include parallelism, perpendicularity and concentricity.
A type of 3D CAD Modeling that represents the volume of an object, not just its lines and surfaces. This allows for analysis of the object's mass properties.
The straight distance from one outside curved surface through the center point in the opposite outside curved surface.
Drawings that convey all of the information needed to manufacture and assemble a design.
A form of pictorial sketch in which two axes are right angles to each other (one vertical, one horizontal) and the depth axis is at an oblique angle.
The point on the horizon where parallel objects appear to intersect due to convergence.
A drawing projected so that the plane of projection of a three-dimensional drawing is at an equal angle to each of the three axes of the object.
An area of relatively dark tone or close lines, dots or hatching producing darkness/shadow in a drawing or picture.
A perspective drawing using one vanishing point.
One point perspective
In a perspective drawing, the imaginary line at eye level used as a construction line.
An imaginary plane in the line of sight on which an image appears.
A view of an object created with one or more vanishing points to the horizon.
The point where the viewer stands to observe the image on the picture plane.
The axis representing height, width and the depth for an isometric drawing.
Drawing using vertical lines and two vanishing points.
Two point perspective
In a perspective drawing, the effect when parallel lines appear to come together in the distance.
American National Standards Institute
International Organization For Standardization
Engineer that develops new fuels.
Engineer responsible for design of electrical circuitry.
A(n) ___________ is a new product, system or process that has never existed before, created by study and experimentation.
