ied final

define problem

identify what needs to be done, find out what users want

generate concepts

coming up with ideas to solve problem

develop solutions

pick one idea and design it

construct and test

build and test prototype

evaluate solution

how can we improve, modify, or rest

present solution

show off the prototype to stakeholders

line graph

track changes

scatter plot

A graph with points plotted to show a possible relationship between two sets of data.

bar graph

a graph that uses vertical or horizontal bars to show comparisons among two or more items

histogram

A graph of vertical bars representing the frequency distribution of a set of data.

pie graph

a graph that shows circles that are "sliced" apart to represent percentages of the total "pie" for particular groups or categories

object line

A heavy solid line used on a drawing to represent the outline of an object.

construction line

Very lightly drawn lines to guide drawing other lines and shapes

hidden line

A line type that represents an edge that is not directly visible.

center line

A line which defines the center of arcs, circles, or symmetrical parts.

4 characteristic that help determine the best front view of an object when sketching it

1. shows longest dimension

2. no hidden lines

3. most stable and natural position

4. shows best shape and contours

through

goes through entire object

blind

partially goes through object

countersink

A conical-shaped recess around a hole that is often used to receive a tapered screw.

counterbore

A cylindrical recess around a hole, usually to receive a bolt head or nut.

clearance fit

space will always results when parts are put together

interference fit

friction will always result when parts are put together

transitional fit

perfect fit between mating part

unilateral tolerance

A tolerance in which variation is permitted in only one direction from the specified dimension.

bilateral tolerance

A tolerance in which variation is permitted in both directions from the specified dimension.

limit dimensions

The largest and smallest possible boundaries to which a feature may be made as related to the tolerance of the dimension.

mean

average

mode

most frequently occurring score

median

Middle number

range

the difference between the highest and lowest scores in a distribution

standard deviation

a computed measure of how much scores vary around the mean score

coincident

allows to make 2 or more entities come together

concentric

when two or more objects share the same center point

parallel

makes any two things parallel

tangent

so what an object moves along a curve
