The Department of Mechanical Engineering offers a broad range of programs leading to the bachelor of science degree in mechanical engineering.
Mechanical engineering has always meant engines and machinery, but the character of modern engines and machinery has changed enormously because of the ever-increasing demands of performance, compactness, reliability, and productivity. The early devices were built by ingenious mechanics who possessed the know-how to reduce ideas to practice. In an increasingly competitive world, traditional know-how and creative ability are as necessary as ever but no longer sufficient. It is also necessary to know why things occur and thus be able to guide the earliest stages of planning. With finite resources and increasing awareness of the environment, mechanical engineers must cope with the undesirable effects of pollution as well as the traditional concerns of efficiency and safety. The tools they need must be more sophisticated.
Mechanical engineering plays a dominant role in a wide spectrum of industries, among them transportation (automotive, rail, air, and marine), heavy machinery (machines producing other machines), the power industry, the environmental industry (heating, ventilation, and air-conditioning), robotics, light precision-machine enterprises (optical, prosthetic devices, mechanical instruments, and the like), and numerous commercial-product industries.
Preparation for a career in mechanical engineering requires a basic understanding of the mathematical, physical, and engineering principles essential to planning, designing, and manufacturing new equipment. The curriculum provides a broad fundamental preparation for direct entry into industry as well as for further professional study. The first part of the curriculum is devoted to mathematics, physics, and chemistry. With this background, fundamental mechanical engineering subjects, such as dynamics, solid mechanics, fluid mechanics, and thermodynamics, are studied, followed by specialized subjects, such as manufacturing, heat transfer, and automatic control. During the final two years design courses, laboratory courses, and project courses allow students to acquire a taste for the complex task of designing, analyzing, and building a piece of “hardware.” In particular, students become aware of the relationships among conceptual design, subsequent analysis (mathematical modeling), manufacturing, systematic experimentation, and final testing. Supporting courses in allied fields of science and engineering broaden technical proficiency, while the elective courses in social sciences, fine arts, history, and philosophy enlarge the background in the problems of humanity.
The program in mechanical engineering is designed to appeal to students with a wide variety of interests and professional goals. By choosing the 4 required elective courses wisely, students can develop a highly personalized curriculum. Some areas of concentration are computer-aided design and manufacturing, fluid mechanics, robotics, systems and control, and tribology. In addition, there are seven concentrations: biomedical engineering, design, energy, intelligent mechanical systems, manufacturing, nanotechnology/MEMS, and solid mechanics.
The biomedical engineering concentration is open to students interested in the biological and medical applications of mechanical engineering procedures. Students in this concentration can also satisfy the entrance requirements of medical schools.
The design concentration focuses on product design with related conceptual and manufacturing processes.
The energy concentration emphasizes the mechanical aspects of energy conversion and management.
The intelligent mechanical systems concentration focuses on the design of devices featuring mechanical hardware interfaces with electronic hardware and software.
The manufacturing concentration is directed toward planning and selecting manufacturing methods, design for manufacture, computer-aided flexible automation and robotics, and increased efficiency and productivity of current and emerging manufacturing technologies.
The nanotechnology/microelectromechanical systems concentration focuses on engineering at nanometer- and micrometer-length scales, including properties of materials and design and fabrication of devices.
The solid mechanics concentration focuses on the study of stress and strain in solid bodies, along with the application of computational methods for stress analysis.
A listing of courses that satisfy the elective requirements may be found in the department office.
A detailed description of facilities in the reconstructed mechanical engineering laboratories is available in the department office.
