Engineering dynamics and vibration: reference frames, rigid body rotation, angular momentum, Lagrange’s equations and multi-degree-of-freedom vibration.
Machines move, rotate and vibrate, and engineers need models that predict how. This course introduces the dynamics and vibration of lumped-parameter models of mechanical systems, in recorded lectures with physical and computational demonstrations, recitation videos and notes: Newton’s laws and reference frames, kinematics and rotational motion, angular momentum and torque, free body diagrams and fictitious forces, rigid body rotation, Lagrange’s equations, and the vibration of single and multi-degree-of-freedom systems.
What You Will Achieve
- Describe the motion of particles and rigid bodies in moving reference frames
- Derive equations of motion with free body diagrams, angular momentum and torque
- Apply Lagrange’s equations to systems of particles and rigid bodies
- Analyze mechanical vibration in single and multi-degree-of-freedom systems using mode superposition

- Velocity, acceleration and rotational motion
- Free body diagrams and fictitious forces
Rigid Body Dynamics
Rotation and how to get equations of motion.
- Angular momentum and torque
- Angular momentum of rotating masses and rigid bodies
- Equations of motion for rigid body rotation
- Lagrange’s equations
Vibration
How mechanical systems oscillate, and how to tame it.
- Mechanical vibration
- Reducing problem vibration
- Multi-degree-of-freedom systems
- Vibration analysis by mode superposition
Course Completion
Job Outlook
Engineering dynamics is used in mechanical, aerospace and automotive engineering, robotics, structural vibration analysis and machine design.
Good for: Engineering learners who want a solid, well-supported course in dynamics and vibration, with full solutions to practice on.
Keep in mind: Each lecture is paired with a reading from the course text, and the small recitation sections were for enrolled students; videos of one section stand in for them.
Bottom line: A complete recorded course in engineering dynamics and vibration, with solved problems and exams.
Frequently Asked Questions
What comes with the lecture videos?
Videos of one professor's recitation sections, recitation notes by another, lecture notes, problem sets and exams, all with solutions, and concept questions that go with the problems.
Can I jump to a specific topic in a lecture?
Yes. Each lecture and recitation video can be watched whole, or you can jump to particular points using the concept links listed below it.
How are the problem sets built?
They combine full problems with multiple-choice concept questions tied to those problems, and you answer the concept questions first.
