Catalog Description & Prerequisites

            214 Dynamics. 3 hrs. Laws of motion, work and energy, impulse and momentum, relative motion.   Computer applications. 3 lec. (PR: ENM213 ; PR: MTH 230)

 

Course Objectives

Traditionally, statics and dynamics are integral components of all undergraduate engineering  curricula.  These courses provide the basics concepts and skills required to complete advanced engineering design and analysis courses and introduce the problem solving process used by engineers.  Consequently, the objective of ENM214 is to introduce the student to the basic concepts listed below by requiring the completion of a significant number of application examples (home work problems).

 

Concept

Kinematics of Particles:

Rectilinear and curvilinear motion

Kinetics of Particles:

Newton’s laws of motion; linear and angular momentum; dynamic equilibrium

Kinetics of Particles:

Force, work, energy, power and efficiency;  conservation of force and energy; impulse and momentum

Kinetics of Systems Particles:

Newton’s laws; linear and angular momentum; impulse and momentum

Kinematics of Rigid Bodies:

Translation and rotation; rotation; relative and absolute motion; acceleration

Kinematics of Rigid Bodies, Forces and Acceleration:

Equations of linear plane motion; angular momentum; systems of rigid bodies

Kinematics of Rigid Bodies, Energy and Momentum:

Work and energy; kinetic energy in plane motion; systems of rigid bodies; conservation of energy; power

D.      Course Policies

1.     Students are strongly encouraged to attend and participate in all class meetings.  However, there are no official penalties for class absences.

2.     Except for extraordinary circumstances (i.e., authorized medical problems) students are required to take exams at the scheduled times and dates.

3.     Homework will be assigned on a daily basis and collected at the beginning of the class period on the date that it is due.   Assignments submitted after the due date will be worth, at most, 50% of the point value of the assignment.

4.     HW assignments should be done on 8.5 x 11”  paper in a neat manner that is easy to read, showing all steps and calculation to each problem.  Answers should be clearly marked and easy to find.  The student’s name and the number of the problem should be shown at the top of each sheet. 

5.     Students are encouraged to work together on HW assignments.  However, cheating will not be tolerated on exams.  Any student caught cheating on an exam will receive a zero on that exam.
