Catalog Data
MEGR 2141. Engineering Mechanics I. This course introduces the principles of particle and rigid body
mechanics with engineering applications; force and moment systems and resultants, equilibrium of
particles and rigid bodies, friction, properties of areas and volumes. (Fall, Spring)
Textbook
Meriam and Kraige, Engineering Mechanics – Statics, 6th Edition, John Wiley & Sons, 2007.
Goal
The objective of this course is to provide students with the tools for analyzing systems in static
equilibrium.
Prerequisites
Phys 2101 and Math 1242 (both with a minimum grade of C).
Academic Integrity:
Exam and homework submissions are to be the student’s own original work. Students have the
responsibility to know and observe the requirements of the UNCC Code of Student Academic Integrity,
policy 105, http://www.legal.uncc.edu/policies/ps-105.html. This code forbids cheating, fabrication or
falsification of information, multiple submissions of academic work, plagiarism, abuse of academic
materials, and complicity in academic dishonesty.
Outcomes
At the completion of the course, the student should be able to:
1. represent and calculate force and moment vectors and their resultants
2. draw free-body diagrams for static systems
3. solve for loads in truss systems using method of joints and method of sections
4. solve for loads in frame/machine systems
5. draw the shear and moment diagrams of beams with concentrated forces, distributed forces,
and couples
6. analyze loads in static systems involving friction
7. calculate the first and second moments of area (centroid and area moment of inertia) by
integration or method of composites with use of the transfer of axis theorem.
Computer usage
It is expected that homework and exam problems will be solved by hand. However, a class project will
be assigned that will require electronic document preparation (text, equations, and figures).

The final exam is scheduled for Monday, 5/7 from 2:00 pm to 4:30 pm. No early final exams will be
administered.
Homework:
• will be assigned weekly
• assignments and solutions will posted in Moodle
• due at the beginning of class on the assigned date
• late submissions will not be accepted unless special arrangements are made with the instructor
in advance
• must include a cover page with your full printed name in the upper right hand corner
• multiple pages must be stapled
• must not be copied from another person or source (this is a violation of the UNCC Code of
Student Academic Integrity)
• solutions must include units
• answers should be boxed
• must show the solution method (not just the answer).
Schedule
The course schedule is tentative and subject to change by the instructor.
