analog

device that uses continuous values of voltages and currents


analog computer model

analog circuit that simulates a physical system


analysis

the process of defining and seeking an answer to a problem


cubesquare law

as an object gets smaller, the volume decreases faster than the area. surfacearea to volume ratio increases with small obj.


digital

device that uses only discrete voltages and currents


engineering design method

a procedure of synthesis, analysis, communication, and implementation


law of diminishing returns

small inputs, the output increases linearly; larger inputs, outputs levels off


application issue

the lack of clarity as to whether a particular act violates a law, rule, or policy


conceptual issue

uncertainity about how it should be codified into clearly definied law, rule, or policy


conflict of interest

engineer's loyalties and obligations may compromised bc of other loyalities


convergence

to tend toward a common solution


diverge

to differ


eminent domain

the right of the gov't to take possesion of private property for public use


engineering ethics

the set of standards engineers should follow


ethical egoism

an act is moral if you act in your own self interest


ethics

concepts of right and wrong behavior


etiquette

the codes of behavior and courtesy


factual issue

uncertainity about morally relevant facts


game theory

a tool for evaluating optimal behavior strategies

E(benefit)(importance)E(harm)(importance)


interaction rules

expected sets of behavior


law

the system of rules established by authority, society, or custom


legal rights

just claims given to all humans through the gov't


moral issue

issue resolved through moral decision


moral rights

just claims that belong to humans


moral theories

framework for making moral and ethical decision


morals

accepted standards of rights and wrong


rights analysis

moral theory that equally respects each human being


ulitarianism

to create the most good for people


vulcanized

to imporve the strength and resiliency of a polymer by bining it with sulfur


whistle blowing

informing authorities of harmful, dangerous, ot illegal activities


application

process whereby appropriate information is identified for the problem at hand


Archimedes' principle

total mass of a floating object equals the mass of the fliud displaced


comprehension

the step in which the proper theory and data are used to actually solve th problem


heuristic

the use of speculative strategies for solving a problem


iterative procedure

repetition of a sequence of steps to solve a problem


manipulative models

a class of problems that have some physical entity that can be used to one's advantage in order to solve a problem


parallelepiped

a solid with six parallelogram faces that are parallel to the opposite face


reductionism

logically break a problem into pieces


actuator

a mechanism that uses pneumatic, hydraulic or electrical signals to activate equipment


concurrent engineering

a design approach in which specialists work together right at the beginning of a project


delphi technique

members of a group are intentionally separated and given the same problem. they return their solutions to the leader, the solutions are pooled , and the group members rate the ideas


evalution matrix

mathmatical evaluation that identifies the best solution by weighing


feasibility study

step of the engineeriing design method where ideas are roughed out


global optimum

the best condition found with constraints


initial capital cost

the purchase price of a product


lifecycle cost

the purchase price and additional costs such as labor, operation, insurance, and maintenance


local optimum

the best condition found w/ contraints

ideds are discussed and then ranked


preliminary design

the step of the engineering design method where some of the more promising ideas are explored in more detail


redundancy

the use of multiple components in which each has the same capabilities


sequential engineering

an approach in which specialists work in compartmentalized manner


chronological strategy

a strategy that gives a historical account of the topic


accurancy

the extent to which the reported value approaches the true value and is free form error


engineering notation

the use of leading zeros for decimal numbers less than 1


error

the differenc between the the reported value and the true value


precision

the extent to which the measurement may be repeated and the same answer obtained


random error

an error that doesn''t result from a measurement methos thatis inherently wrong


rounding error

rounding in intermediate calculations which results in an incorrect final answer


scientific notation

numbers expressed in terms of decimal point


significant figure
