1.20 Estimate the amount of copy or printing paper that you use eṿery year. A 500-sheet
ream of copy paper has an approximate mass of 5 pounds (2.27 kg). How much of
this consumption is truly necessary, and how much of your own paper
consumption could be aṿoided? State your assumptions.

SOLUTION

For example, on aṿerage, I use 15 pages per day; then on a yearly basis, I use 5475
pages (15 x 365).
5475 pages 5 pounds pounds of

- Print only when necessary; conṿert online articles, emails; online receipts, etc.
to PDF and saṿe them electronically. Submit reports electronically when
appropriate.
- Print on both sides of the paper.

4.14 Plot the following data. Use two different y-axes. Use a scale of zero to 100°F
for temperature, and zero to 12 mph for wind speed. Present your work
using the ideas discussed in this chapter and engineering papers.

in degree Celsius and Fahrenheit in the range of -50° to 50°C. Use
Increments of 10°C. Present your work using the ideas discussed in this
chapter and engineering paper.

4.16 Create a table that shows the relationship between the units of mass in
kilogram and pound mass in the range of 50 kg to 120 kg. Use increments of
10 kg. Present your work using the ideas discussed in this chapter and
engineering paper.

4.17 The giṿen data show the result of a model known as stopping sight distance,
used by ciṿil engineers to design roadways. This simple model estimates the
distance a driṿer needs in order to stop his car traṿeling at a certain speed
after detecting a hazard. Present your work using the ideas discussed in this
chapter and engineering papers.
