Bachelor of Science in Mechanical Engineering

Mechanical engineers may choose from among many different activities in their careers, according to their interests and the changing needs of society.  The BS in Mechanical Engineering prepares students for work in many fields including energy transport, design of machinery, and manufacturing.

The curriculum leading toward the bachelor of science in mechanical engineering combines a broad base in mathematics, physical sciences, and the engineering sciences (mechanics of solids, materials, dynamics and fluid, thermal and electrical sciences), including laboratory.  Special emphasis is placed on the practice of modern Integrated Product Development, combining state-of-the-art computer-aided design and manufacturing methods in a business oriented framework.  Several specific application fields are chosen toward the end of the program in the form of four or more courses elected from a wide variety of 300-level offerings.  Courses in mechanical engineering and engineering mechanics are equally available.

The course requirements for a B.S. degree in mechanical engineering are listed below.  In addition to required mathematics, physics, chemistry and basic engineering courses, the program includes a minimum of seven courses in humanities and social sciences (see humanities/social sciences), two free electives and five approved electives.  The total graduation requirement is 129 credits.

We strongly recommend that all graduating seniors register for the Fundamentals of Engineering (FE) Exam to begin the process of becoming a certified Professional Engineer. More information regarding the FE can be found here.

Note: Our BSME program is accredited by the Accreditation Board for Engineering and Technology (ABET).

  • Free electives: 6 credit hours in any subject area are required.


Cooperative Education (Co-Op) Program


Co-Op is available for undergraduates in the P.C. Rossin College of Engineering and Applied Science; the program provides eight months of paid, full-time work experience, bridging the gap between engineering theory and application and allowing students to graduate within a four year timeframe. Because of the rigorous academic schedule, the program is selective.

The Co-Op schedule provides for interviews and selection by the companies in the spring semester of the sophomore year. Those students selected attend Lehigh for a challenging summer schedule of junior-level coursework, then begin their first work rotation with the sponsoring company in mid-August. This rotation will last until mid-January when the student returns to Lehigh for the second semester coursework of the junior year. The Co-Op experience is completed with a second work rotation the following summer (mid-May through August). Students earn 3 free elective credits per successful work assignment for a total of 6 free elective credits.

To participate in the Co-Op program you must rank in the top third of the engineering class after three semesters of study and attend a summer program between the sophomore and junior years. See your advisor or contact the Co-Op Faculty Liaison for further details.



Humanities/Social Sciences (HSS)Requirement for all Accredited Engineering Majors


Basic Requirement: English and Economics. Three courses totaling a minimum of ten credit hours: Students must complete English 1 (or 3), English 2 (or 5, or 11) and Economics 1. Students with advanced placements in English 1 usually take English 11 to complete the English requirements.

Advanced Requirement: Breadth and Depth. 13 credits in courses designated as HU (humanities) or SS (social science), with the following restrictions:

  1. Depth: At least eight credits must be in a common discipline and from the same department or program. At least three of these credits must be at the 100-level or above, or at the intermediate level or above for a single modern foreign language.
  2. Breadth: At least three credits in a discipline different from, and not cross-listed with, the discipline employed to satisfy the concentration requirement above.
  3. At least three credits must be designated as HU.
  4. None of the courses used for HSS can be taken Pass/Fail.
  5. None of the course can be one-credit courses.
