Flashcards in Engineering Deck (20):
1

Engineering Psychology

The design of machines and equipment for human use and the appropriate human behaviours for the efficient operation of the machines

Also called human factors, human engineering, and ergonomics

2

Time and motion study

An early attempt to redesign work tools and to reshape the way workers performed, routine, repetitive jobs

3

Frederick W Taylor

Observed workers using many different shovels

4

Gilbreths

Interested in mechanics of the job, goal to eliminate all unnecessary motion

Frank worked as a bricklayer

5

Efficiency experts

Time and motion experts that apply gilbreths techniques to many jobs

6

Person machine system

System in which human and mechanical components operate together to accomplish a task

7

Quantitative visual display

Present a precise numerical value, such as speed, altitude, temperature

-can be analog or digital

8

Analog display

On many clocks or speedometers, contains range of numbers and arrow

9

Digital display

Displays only number needed at the moment

10

Qualitative visual displays

Present range rather than precise numerical value

-frequently used to show whether components like engine temp are operating in safe range

-also shows whether values increasing or decreasing

-often color coded

11

Check reading visual displays

Tell operator whether system is on or off, safe or unsafe, normal or abnormal

-most common is warning light

12

Airbus

Largely computer controlled and limits actions pilots are allowed, pilots are unable to override computer

13

Boeing airplane

Pilots can take control of plane at anytime to override computer

14

US Army M1 Abrams tank

Tank designed without thinking of users

15

Human anthropometry

Focuses of measurement of physical structure of human body

16

USS Stark

In navy in Persian gulf some guy turned off audio alarm cause it was annoying, so a jet plane from Iraq was undetected and killed people

17

Controls should satisfy two criteria

Control body matching

Control task compatibility

18

Control task compatibility

A control action should imitate the movements it produces - movement and machines response are parallel

19

OnStar

Gps based collision notification system that shows location of car and alerts authorities when airbag deploys

20

ASIMO

advanced step in innovative mobility

A robot that conducted an orchestra
