What is a primary source?
An original source. Primary sources are distinguished from secondary sources, which cite, comment on, or build upon primary sources.
Assembly
A group of machined or handmade parts that fit together to form a self-contained unit.
Degree of Freedom
The variables by which an object can move. In assemblies, an object floating free in space with no constraints to another object can be moved along three axes of translation and around three axes of rotation. Such a body is said to have six degrees of freedom.
Function
1. A relationship from one set (called the domain) to another set (called the range) that assigns to each element of the domain exactly one element of the range. 2. The action or actions that an item is designed to perform.
Model
A visual, mathematical, or three-dimensional representation in detail of an object or design, often smaller than the original.
What is a secondary source
A source of material that takes existing work and presents some parts, such as a summary, as their interpretation of the original work and provides citations of referenced work.
Assembly Drawing
A drawing that shows parts of an item when assembled
Design Brief
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.
Geometric Constraint
Constant, non-numerical relationships between the parts of a geometric figure. Examples include parallelism, perpendicularity, and concentricity.
Origin
A fixed point from which coordinates are measured.
What is the Development Process
Plan
Design
Create and Test
Evaluate the Solution
Document and Present
Cartesian Coordinate System
A rectangular coordinate system created by three mutually perpendicular coordinate axes, commonly labeled X, Y, and Z.
Design Statement
A part of a design brief that challenges the designer, describes what a design solution should do without describing how to solve the problem, and identifies the degree to which the solution must be executed.
Marketing
The promotion and selling of products or services.
Packaging
Materials used to wrap or protect goods.
Why is having a team so important to the development process
Component
A part or element of a larger whole.
Domain
The set of input values of a function.
Mathematical Modeling
The process of choosing and using appropriate mathematics and statistics to analyze empirical situations, to understand them better, and to improve decisions.
GPU
a specialized processor originally designed to accelerate graphics rendering
Annotate
To add explanatory notes to a drawing.
Computer-Aided Design or Computer-Aided Drafting (CAD)
1. When used in the context of design: the use of a computer to assist in the process of designing a part, circuit, building, etc. 2. When used in the context of drafting: the use of a computer to assist in the process of creating, storing, retrieving, modifying, plotting, and communicating a technical drawing.
Extrusion
1. A manufacturing process that forces material through a shaped opening. 2. A modeling process that creates a three-dimensional form by defining a closed two-dimensional shape and a length.
Mock-up
A model or replica of a machine or structure for instructional or experimental purposes. Also referred to as an Appearance Model.
CPU
Central Processing unit
