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
shows longest dimension
no hidden lines
most stable and natural position
shows best shape and contours
3 guiding principles for properly dimension a multiview drawing

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
