I. Abstract

The World Punkin’ Chunkin’ contest is a yearly affair of the Chamber of Commerce of the city of Lewis, Delaware. Department of Technology students entered the competition with a human powered, 20 ft long sling-shot type device and won the first place by throwing an 8-lb pumpkin 246 feet away.

The design of a pumpkin thrower was assigned to three Mechanical Engineering Technology students as a project for senior level "ETME 475 - Mechanical Systems Design" course. As a first step, each student worked on their own pumpkin thrower. During the final phase, students worked on the design and manufacturing of the different parts of the project. During the early Fall semester one student, with faculty supervision, worked on the project to redesign the pouch and tune the system. Students from the Engineering Society have also helped to set it up for tests and decorations. Competition day was of course a Department affair.

Students enjoyed working on this good engineering applications project. The Project required them to use their mathematics, machine design, computer programming, engineering analysis and reasoning, and dynamics knowledge.

This paper conveys our experiences with the project, shares my experiences in how to guide students towards a common goal in a systems design course and how to lead them to finish the project on time.

II. Introduction

Students in Mechanical Engineering Technology program at the University of Maryland Eastern Shore are required to take a senior level "ETME 475 - Mechanical Systems Design" course during their last semester. This course is 3 credit hours. Two hours are used for lecture and two hours are used for laboratory. Depending on who is taking the course and the type of projects planned, either no text book is required or Dr. Dieter’s "Engineering Design" [1] textbook is used. The text is
