This course is an advanced study of bodies in motion as applied to engineering systems and structures. We will study the dynamics of rigid bodies in 3D motion. This will consist of both the kinematics and kinetics of motion. Kinematics deals with the geometrical aspects of motion describing position, velocity, and acceleration, all as a function of time. Kinetics is the study of forces acting on these bodies and how it affects their motion.
To be successful in the course you will need to have mastered basic engineering mechanics concepts and to have successfully completed my course entitled Engineering Systems in Motion: Dynamics of Particles and Bodies in 2D Motion.” We will apply many of the engineering fundamentals learned in those classes and you will need those skills before attempting this course.
While no specific textbook is required, this course is designed to be compatible with any standard engineering dynamics textbook. You will find a book like this useful as a reference and for completing additional practice problems to enhance your learning of the material.

Course Introduction; Angular Velocity; Angular Acceleration In this section students will learn to derive the "derivative formula." We will define angular velocity for 3D motion and learn to determine and solve for the Angular Acceleration for a body.
Velocities in Moving Reference Frames; Accelerations in Moving Reference Frames; The Earth as a Moving Frame In this section students will learn about velocities in moving reference frames, accelerations in moving reference frames, and the Earth as a moving frame.
Eulerian Angles; Eulerian Angles Rotation Matrices; Angular Momentum in 3D; Inertial Properties of 3D Bodies In this section students will learn about Eulerian Angles rotation matrices, angular momentum in 3D, and intertial properties of 3D bodies.
Translational and Rotational Transformations of Inertial Properties; Principal Axes and Principal Moments of Inertia In this section students will learn about translational and rotational transformations of inertial properties, and principal axes and principal moments of inertia.
Motion Equations Governing 3D Rotational Motion of a Rigid Body (Euler Equations) In this section students will learn to develop Euler Equations for 3d motion and solve for the motion of a rigid body undergoing 3D rotational motion.
3D Impulse-Momentum Principles; 3D Work-Energy Principles In this section students will learn to develop and apply the principle of impulse-momentum and about 3D work-energy principles.
MOOCs stand for Massive Open Online Courses. These arefree online courses from universities around the world (eg. StanfordHarvardMIT) offered to anyone with an internet connection.

How do these MOOCs or free online courses work?
MOOCs are designed for an online audience, teaching primarily through short (5-20 min.) pre recorded video lectures, that you watch on weekly schedule when convenient for you. They also have student discussion forums, homework/assignments, and online quizzes or exams.
He explains everything extremely well, and the class videos are always available so you can actually review the material at any time. He cares about his students and grades fairly. If you stay up to date on video lectures, the class should be manageable.
This was my first proper course on kinematics and dynamics of rigid bodies outside self study. It helped me consolidate my understanding of the subject and (I feel) perform better at college when I actually took the classroom course.
One of the best Mechanical Engineering courses I have ever taken. Dr. Whiteman does an excellent job explaining the material starting from first principals all the way to application so that it is easy to follow along and understand.
This specialization has allowed me to look at the world through the eyes of an engineer, and I believe that taking these classes will be a huge advantage in my first year at Colorado School of Mines. Well done Dr. Whiteman!
Thomas Hocompleted this course, spending 5 hours a week on it and found the course difficulty to be medium.
This is very nice course on 3D dynamics. All concepts explained very well, the difficulty of mathematics is appropriate. Highly recommended to student or engineer that needs to review dynamics for their job.
