Textbook

  • Engineering Mechanics: Dynamics, R.C. Hibbeler, 14th ed., Prentice Hall, 2015.

Course Objectives and Emphasis

The primary goal of this course is to provide the students with a foundation in the theory and principles of Dynamics. The students are expected to build upon previously acquired skills in mathematics and physics to solve practical problems of Dynamics. The course objectives are

  • Apply a general analysis approach to solving kinematics and kinetics problems.
  • Draw complete free body diagrams.
  • Kinematics: define and calculate the displacement, distance, velocity and acceleration for particles in rectilinear and curvilinear motion. Define and calculate the linear and angular velocities and accelerations for systems of 2D rigid bodies in translation, rotation about a fixed axis, and general planar motion.
  • Kinetics: calculate the mass moment of inertia (about the center of mass and about a point other than the center of mass). Solve 2D kinetics problems using force-acceleration, work-energy and impulse-momentum methods.

Course Outcomes of Instruction

  • Students demonstrate the ability to analyze the geometric aspects of the motion of particles and rigid bodies (kinematics), as well as the forces that cause that motion (kinetics).
  • Students will demonstrate the ability to define practical dynamics problems by identifying known and unknown quantities, formulate the problem by presenting it using free-body diagrams, and successfully solve it using the proper engineering techniques.
  • Students demonstrate the ability to design moving (and vibrating) systems to meet specific performance criteria.

Course Student Outcomes (ABET)

  • An ability to apply knowledge of mathematics, science, and engineering,
  • An ability to identify, formulate, and solve engineering problems,
  • An ability to use the techniques, skills, and modern engineering tools necessary for engineering practice.

Fundamentals of Engineering Exam (FE)

One of the objectives of this course is to prepare the students for the FE Exam. Therefore, in certain assignments you will be required to use the FE Handbook. FE includes questions in the following areas related to Dynamics

  • Linear motion (e.g., force, mass, acceleration, momentum),
  • Angular motion (e.g., torque, inertia, acceleration, momentum),
  • Mass moment of inertia,
  • Impulse and momentum applied to particles and rigid bodies,
  • Work, energy, and power applied to particles and rigid bodies,
  • Friction.
