#### Information and Departmental Plan of Study

The Department of Mechanical and Aerospace Engineering recognizes that students may have a variety of career objectives. Some may intend to enter industry directly in an engineering capacity or to continue studies in graduate school in engineering or applied science. Others may wish to take an engineering program in preparation for careers in business, law, or medicine. The department offers sufficient flexibility to students planning an undergraduate program that meets any of these objectives and builds a foundation of engineering disciplines and associated problem-solving skills. The disciplines of solid and fluid mechanics, thermodynamics, dynamics, control systems, materials, and applied mathematics, combined with the experience of engineering design, are the core of the department's curriculum. Both the mechanical and aerospace engineering programs are accredited by the Engineering Accreditation Commission of ABET.

#### General Requirements

Requirements for study in the department follow the general requirements for the School of Engineering and Applied Science. In addition, the following four courses and one laboratory are normally completed by departmental students before entry into the junior year.

*Mechanical and Aerospace Engineering*

Each student's program is planned individually in consultation with the class adviser. Suggested plans of study for each of the programs in the department are available from the departmental representative.

#### Program of Study

The department offers two programs of study: mechanical engineering and aerospace engineering. These programs draw on courses in the underlying fundamental sciences and mathematics during the first year, which lead to broad introductory engineering science courses during the second year, where students are introduced to the creative application of this knowledge to the solution of technical problems. Aspects of engineering design, the process of devising a system to meet a need, are introduced to the student through laboratories in the second year and continue through the upperclass years. During the third year all students take a two-semester design sequence as well as further engineering science courses dealing with analysis and application in the areas of energy sources and power systems, structures, aerodynamics and flow systems, and the dynamics of machines and their control. The introduction of design during the third year, combined with further depth in engineering science, enables students to undertake realistic design projects during their senior year. The programs are designed to prepare the graduate for an engineering career and give him or her the ability to continue to grow professionally.

**Mechanical Engineering. **This program deals with the analysis and design of machines, their motion, power sources, and control. The curriculum is based on dynamics, thermodynamics, and the study of the structure and behavior of fluid and solid materials; it is accredited by ABET. Students are exposed to the process of engineering design through 321 Engineering Design, 322 Mechanical Design, or 412 Microprocessors for Measurement and Control, and one additional design elective.

All mechanical engineering students must take:

#### Independent Work

At least one semester of independent work as applied science research or an engineering project is required. This may be satisfied by a semester of independent work (339 or 340). If approved by the departmental representative, an independent work project may satisfy a portion of the design requirement II. B. (339D, 340D). 339 and 339D are offered in the fall, and 340 and 340D are offered in the spring. A year-long senior project (440) or senior thesis (442) or senior project with design (440D) or senior thesis with design (442D) also meets this requirement. Students are strongly encouraged to select the year-long project or thesis option. Senior projects are intended for teams or groups while the senior thesis is intended for individuals. For the senior project or thesis, a final grade is issued in the spring.

#### Preparation for Graduate Study

Students who are considering graduate work in applied science may elect the engineering physics option by combining the engineering courses in the department with the requirements of the interdepartmental engineering physics program.

**Program in Sustainable Energy. **This program provides an understanding of Earth, global climate, and environmental change from the perspective of engineering, technology, and policy. The future of societies, the global economy, and the global environment depend on collaborative research into renewable energy, alternative fuels, advanced energy conversion and storage systems, technology transfer to developing countries, and prudent judgment on policies to support sustainable energy technology. Innovations and inventions require multidisciplinary approaches and entrepreneurship, as well as grounding in theory and practice, in topics that are not covered by a single department. This certificate program offers an integrated set of core and elective courses, introducing students to fundamental concepts, providing depth in specific fields of interest, gaining laboratory and site visit experiences, and setting the stage for further work in the field. See the Program in Sustainable Energy entry or view program information online.

**Program in Engineering Physics. **Students with a strong interest in applied science may combine their studies in the department with courses in physics through the interdepartmental Program in Engineering Physics. Many of the requirements of that program may be applied toward the fulfillment of the departmental requirements. For example, PHY 205 or PHY 207 may be substituted for MAE 206 Introduction to Engineering Dynamics. The program's mathematics requirement is identical to that of mechanical engineering. Aerospace engineers will need a second 300- or 400-level mathematics course.

**Program in Robotics and Intelligent Systems. **Robotics and intelligent systems have become focal points for research and development, and they are central to advances in manufacturing technology. New approaches for analysis, design, and synthesis of systems are being developed using symbolic representation of knowledge, electronic neural networks, and parallel supercomputers. Students have an opportunity to learn the theory and practice of automation and to pursue independent study projects in related areas. The mechanical and aerospace engineering department offers a number of courses in this area and is preparing a new generation of engineers in robotics and intelligent systems. For more information, see the Program in Robotics and Intelligent Systems entry or view program information online.

**Program in Materials Science and Engineering. **The materials concentration in mechanical engineering is designed to provide a coherent understanding of the structure, properties, and performance of materials from a mechanics and materials perspective. The materials concentration will provide a foundation in basic and applied science, as well as an introduction to the design and applications of materials. Students are given the opportunity to specialize in areas such as structural materials, biological materials, micro- and nanotechnology, and materials modeling and simulations. This can be achieved by taking a sequence of electives drawn from different departments, and also by engaging in a materials-related senior thesis topic designed to facilitate the specializations. This course of study will prepare students for graduate education in a wide range of areas, or the beginning of a professional career in materials engineering. Students electing this concentration will receive a degree in mechanical engineering. Students are encouraged to simultaneously participate in the Program in Materials Science and Engineering. Most students in this concentration normally take:

MAE 324 Structure and Properties of Materials

MAE 325 Structural Analysis and Finite-Element Methods

MAE 344 Introduction to Bioengineering and Biomedical Devices

MSE 302 Laboratory Techniques in Materials Science

**Other Programs. **Students in mechanical and aerospace engineering with an interest in applied statistics or operational research, in addition to their departmental studies, may wish to follow the Program in Engineering and Management Systems. Students may also wish to pursue the Program in Engineering Biology or the Program in Applied and Computational Mathematics. Some of the program courses may also satisfy departmental requirements.

**Energy and Environmental Studies. **Students with an interest in energy conversion and the generation and control of environmental pollutants normally take:

328 Energy for a Greenhouse-Constrained World

423 Heat Transfer

427 Energy Conversion and the Environment: Transportation Applications
