Welcome to the ENGINEERING.com Challenge #1. This first challenge (yes, more are to follow) is a refresher on some basic engineering, algebra and physics principles. Most of these concepts are referenced in first year engineering textbooks.

Hint: Some of these require a little "out of the box" thinking. But as an engineer that shouldn't be a problem.

Instructions: For each question fill in the appropriate answer. The answer box will turn green if your response is correct and red if incorrect. Take as much time as you need.
