Tech Bowl 2

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
