Chapter 1: Introduction to the Engineering Profession
1.20 Estimate the amount of copy or printing paper that you use every year. A 500-sheet ream
TU
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
avoided? State your assumptions.

SOLUTION

For example, on average, I use 15 pages per day; then on a yearly basis, I use 5475 pages
TO
(15 x 365).
5475 pages 5 pounds pounds of paper
( )( ) = 54.75
year 500 pages year

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

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