Bergen Community College Division of Math, Science and Technology Department of Physical Sciences Course Syllabus PHY 294 Engineering Mechanics Semester and year: Course Number: Meeting Times and Locations: Instructor: Office Location: Phone: Office Hours: Email Address: Course Title and Number: Engineering Mechanics, PHY 294 Prerequisites: Calculus III, MAT 282; Physics I, PHY 280; (or PHY 190) with grades of "C" or better. Course Credits: 4 Course Hours: 4 lecture hours Course Description: Engineering Mechanics is a study of the state of rest or motion of bodies under the action of forces. This course builds a foundation of analytic capability for the solution of a great variety of engineering problems. Topics covered include the statics and dynamics of particles and rigid bodies. Student Learning Outcomes/Behavioral Objectives The student, drawing upon knowledge and skills previously acquired in the prerequisite courses, will begin to synthesize that important material. The student will also demonstrate the following skills: 1. Precise plan the solution to a physical problem by paying strict attention to the very finest of details. 2. Precise use of coordinate systems advantageously in any given problem. 3. Precise use of mathematical symbols, diagrams, graphs, and sketches. 4. Precise use of the laws of statics and dynamics with appropriate mathematics using precise diagrams and critical thinking. Course Grades/Evaluation Methods: The grade for the course is weighted according to the following scheme: 1. Three or more non-cumulative (modular) "hourly" exams and possibly quizzes... 60% 2. Final Exam (Cumulative)... 40% Materials and Supplies: In addition to the required text a pocket-sized calculator (solar cell recommended to avoid battery failure at crucial times) is recommended having advanced mathematical functions. Graphing capability would be advantageous. Required Text: Engineering Mechanics, by J. L. Merriam and L. G. Kraige, John Wiley and Sons, 7th edition, 2011.
