Bachelor of Science in Engineering Mechanics

The curriculum in engineering mechanics is designed to prepare students for careers in engineering research and development, and is especially appropriate for students wishing to specialize in the analysis of engineering systems.  In many industries and governmental laboratories there is a demand for men and women with broad training in the fundamentals of engineering in which engineering mechanics and applied mathematics play an important role.

The first two years of the curriculum is the same as that in mechanical engineering. One of the advantages of the curriculum is the flexibility it offers through 18 credits of technical and six credits of personal electives in the junior and senior years.  Beyond the sophomore year there are required courses in dynamics, solid mechanics, fluid mechanics, heat transfer, principles of electrical engineering, mathematics, vibrations, and senior laboratories or projects.  It is recommended that the electives be chosen either to concentrate in areas such as applied mathematics and computational mechanics, solid mechanics, engineering materials, and fluid mechanics or to obtain further depth in all areas.  The academic advisor for the engineering mechanics program will provide guidance in formulating the student’s goals and choosing electives.

In addition to the required and elective courses in mathematics, sciences and engineering, the B.S. degree program in engineering mechanics includes a minimum of seven courses in humanities and social sciences (see humanities/social sciences).  The total graduation requirement is 127 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.

Engineering Mechanics Electives

  • Humanities/Social Sciences: A total of 17 credits of electives in humanities and social science, which must include ECO 1. (Note that these electives are in addition to the 6 hours of required freshman English.) See description of HSS below.
  • ENGR. Elective A: Two, 3-credit courses selected from the following: MECH 302, MECH 305, ME 304, ME 322, ME 331, or ME 343
  • ENGR. Elective B: Four, 3credit courses selected from any ME 300/MECH 300-level course or an engineering/science/ mathematics course, as approved by the Department Chair, excluding ME 310.
  • Free electives: 6 credit hours of 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.
