Governor’s SchoolEngineering Specialty Instructors Prof. Will Schleter Wayne Pfeiler
Objectives • Introduce Science and Math Fundamentals for Engineering • Provide Exposure to Different Engineering Disciplines • Learn, Participate in, and Practice the Engineering Design Process • Learn and Have Fun!
What is Engineering? • Driving a train? • The application of scientific principles to practical ends as the design, construction, and operation of efficient and economical structures, equipment, and systems. • “Using science and math to figure out how to make stuff and do things.” • Problem Solving…
Example x • A protective liner exactly 12 meters wide is available to line a channel for conveying water from a reservoir to downstream areas. If a trapezoidal-shaped channel is constructed so that the liner will cover the surface completely, what are the values for x and that will provide the maximum water flow?
