Students must be proficient in engineering computations including numerical methods in Matlab. Laboratory Software Needs: Matlab

None.

Contributes to Engineering Topics Courses of Civil Engineering and Environmental Engineering majors. Contributes to FE Exam Preparation: Textbook includes sample FE Exam problems, and these appear on quizzes.

Students work in teams to design a cart that is propelled by a jet of water from a pressure thank. Students compete against other teams from class, and the objective is to: (a) cross the finish line in the shortest time and (b) build a computer model that accurately predicts the race time. Teams are responsible for constructing the cart, configuring the pressure and water level in the tank, configuring a nozzle for the jet, and building a computer model of the cart/jet system.
