Induction
The production of an electric or magnetic state by the proximity (without contact) of an electrified or magnetized body
Inexhaustible Energy
An energy source that will never run out
Kinetic Energy
Energy which a body possesses by virtue of being in motion
Nonrenewable Energy
A resource that cannot be replaced once used
Ohm
The unit of electric resistance in the meter-kilogram-second system of units. Symbolized as Ω
Ohm's Law
States that the direct current flowing in an electric circuit is directly proportional to the voltage applied to the circuit
Parallel Circuit
A closed electrical circuit in which the current is divided into two or more paths and then returns via a common path to complete the circuit
Potential Energy
The energy that a piece of matter has because of its position or nature or because of the arrangement of parts
Power Converter
Changes one form of power to another
Power Grid
A system that links electricity produced in power stations to deliver it to where it is needed
Renewable Energy
A resource that can be replaced when needed
Resistance
The opposition that a device or material offers to the flow of direct current
Work
A result of a force moving an object a certain distance
Turbine
A machine for producing power in which a wheel or rotor is made to revolve by a fast-moving flow of water, steam, gas, or air
Power
The rate at which work is performed or energy is expended
Rotor
The rotating member of an electrical machine
Series Circuit
A circuit in which all parts are connected end to end to provide a single path of current
Volt
The unit of potential difference symbolized as V
Voltage
The potential difference measured in volts. The amount of work to be done to move a charge from one point to another along an electric circuit
Accuracy
The condition or quality of being true, correct, or exact; precision; exactness.
Assembly
A group of machined or handmade parts that fit together to form a self-contained unit.
Brainstorming
A group technique for solving problems, generating ideas, stimulating creative thinking, etc., by unrestrained spontaneous participation in discussion
Component
A part or element of a larger whole
Consensus
A general agreement.
Constraint
A limit to a design process. Constraints may be such things as appearance, funding, space, materials, and human capabilities.
Decision Matrix
A tool for systematically ranking alternatives according to a set of criteria.
Design Brief
A written plan that identifies a problem to be solved, its criteria, and its constraints.
Design Modification
A major or minor change in the design of an item, effected in order to correct a deficiency, to facilitate production, or to improve operational effectiveness.
Design Process
A systematic problem-solving strategy, with criteria and constraints, used to develop many possible solutions to solve a problem
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,
Designer
A person who designs any of a variety of things. This usually implies the task of creating drawings or in some way using visual cues to organize work.
Open-Ended
Not having fixed limits; unrestricted; broad
Pictorial Sketch
A sketch that shows an object's height, width, and depth in a single view.
Problem Statement
A part of a design brief that clearly and concisely identifies a client's or target consumer's problem, need, or want.
Purpose
The reason for which something is done or for which something exists.
Sketch
A rough drawing representing the main features of an object or scene and often made as a preliminary study.
Solid Modeling
A type of 3D CAD modeling that represents the volume of an object, not just its lines and surfaces
Target Consumer
A person or group for which product or service design efforts are intended.
Team
A collection of individuals, each with his or her own expertise, brought together to benefit a common goal.
Axial Stress
A force with its resultant passing through the centroid of a particular section and being perpendicular to the plane of the section. A force in a direction parallel to the long axis of the structure
Breaking Stress
The stress required to fracture a material whether by compression, tension, or shear
Compression
When a material is reduced in volume by the application of pressure; the reciprocal of the bulk modulus
Deformation
Any alteration of shape or dimensions of a body caused by stresses, thermal expansion or contraction, chemical or metallurgical transformations, or shrinkage and expansions due to moisture change
Destructive Testing
Test methods used to examine an object, material, or system causing permanent damage to its usefulness
Elastic Limit
Maximum stress that a material will withstand without permanent deformation
Elongation
The fractional increase in a material's length due to stress in tension or thermal expansion
Factor of Safety
The ratio of actual strength to required strength
Failure Point
Condition caused by collapse, break, or bending, so that a structure or structural element can no longer fulfill its purpose
Fatigue
The loss of the load-bearing ability of a material under repeated load application, as opposed to a single load
