Additional Problems

The following problems combine an assignment in which you will learn more about one of the topics in this chapter with an opportunity to improve your written communication skills. $($Perhaps your professor will even select some of the written reports for oral presentation in class.$)$ Each report should include at least two references, so you will want to learn how to use library computers to locate reference information. Prepare your report using word$-$processor software. If you do not already know how to use a word processor, ask your professor for guidance or visit your university's Web site for links to resources on campus.

$14.$ Write a short report on one of these outstanding engineering achievements:

Analytical Engine

Global Positioning Systems

Composite materials

Application satellites

Mars Orbital Camera

CAD$/$CAM

Fiber optics

CAT scans

A good starting point for finding references is the World Wide Web and your local library.
