Register Description: A basic engineering mechanics course concerned with the equilibrium of nondeformable bodies at rest or moving with a constant velocity on a straight path. Free body diagrams, Newtonian mechanics, vectors and the calculus are used to solve problems throughout the course. Topics include force vectors and systems, equilibrium, trusses, frames, friction, center of gravity, centroids, moments of inertia and fluid hydrostatics. Prerequisites: [PHY 120 & (MTH 112 or MTH 113)] or IMP 120.

Required Text: Hibbeler RC. Engineering Mechanics: Statics, 14th Edition. Prentice Hall, 2016.

Homework: Homework (HW) problems have been suggested according to the schedules provided in this syllabus but will not be collected. Solutions will be available for all problems. Exam problems will be very much like these problems. The most successful students will work as many additional problems in the text as possible.

Exams: Three exams will be administered, two midterm exams during a lecture period and one final during the final exam period. A single sided formula sheet prepared by each student will be allowed for each exam.

Office Hours: TTH 10:45-12:00PM, or by appointment. The instructor can see students whenever free.

Grades: Course grades will be determined from: 30% each term exam and 40% final exam, and using this scale:

93-100 = A

90-92 = A-

87-89 = B+

83-86 = B

80-82 = B-

77-79 = C+

73-76 = C

70-72 = C-

60-69 = D

0-59 = F

Learning Objectives: Upon successful completion of this course, students will be able to:

Identify and formulate elementary level engineering problems related to the equilibrium of particles and rigid bodies in the conceptual form as well as in terms of mathematical and physical models
Apply basic Newtonian mechanics and energy methods to the analysis of particle and rigid body statics
Effectively generalize the fundamentals of statics and extrapolate those fundamentals to problems not specifically covered in this course

Relationship of Course to ABET Program Outcomes: Upon successful completion of this course, students will have:

an ability to apply knowledge of mathematics, science and engineering
an ability to identify, formulate and solve engineering problems
an ability to communicate effectively
an ability to use the techniques, skills and modern engineering tools necessary for engineering practice

Attendance & Punctuality: Each student will be responsible for knowledge of all scheduling changes and announcements made in class. Without exception, no prior, late or makeup assignment will be administered, accepted or allowed without a College approved excuse.

Classroom Decorum: Consider the classroom as our place of business (that is not to say that we will not have a laugh or have fun). Arrive in time so that you are prepared to work when the class period begins. Do not begin packing to leave until class is dismissed. Food is not allowed in the classrooms. Refrain from rising and leaving during class for a break unless it is absolutely necessary. You have completed your exam if you leave the room during the exam.

Recording: No audio, photographic or video recording may be made in class or in the office of the instructor without the expressed consent of the instructor.

Department Statement on Academic Honesty: The highest levels of ethical behavior are required of those in the profession of engineering and, by extension, of those preparing themselves to enter the profession. Furthermore, ethical behavior, especially in the area of academic honesty, is critically important to the entire educational and academic mission of the College. Therefore, the Mechanical Engineering Department takes matters of academic honesty very seriously. Further information on Union's Honor Code can be found here: honorcode.union.edu.

Students With Disabilities: Contact the Office of Student Support Services for appropriate documentation to present to your professor should you require reasonable accommodations for your disability. It is your responsibility to arrange for any accommodations in a timely manner.
