"I once tried marijuana but I never exhaled." (Hugh Downs)


And to this I say:
Legalize marijuana and we'll have strong ass rope and happy people lots of
paper and save our trees to boot....then who the hell will care about these
kinds of stupid test questions....
sorry i just couldn't resist...:~)

Rope Strength
Manufacturers consider several different features when making rope for
various uses. In this problem, you will graph or find relationship
between these different features. (To answer this question, you will
need to draw 3 graphs in your Student Response Booklet [VS: I shall
abbreviate this as SRB]).
a. In your SRB, copy the labeled axes below and sketch a graph showing
that if you double the length of a piece of rope, you double its weight.
[Image: a rectangular axes pair for Weight vs. Length]
b. In your SRB, copy the labeled axes below and sketch a graph showing
that if the breaking strength of a rope is not affected by its length.

c. In your SRB, copy the labeled axes below and sketch a graph showing
that if you double the diameter of a rope, you multiply its breaking
strength by 4.

d. The table of data below shows the relationship between the diameter
of a rope and its breaking strength. Using the data, write a formula for
the breaking strength (S) in terms of the diameter (d).
[Table:
diameter (in mm): 0 2 4 6 8 10 12
