Hi, I'm Dr. Wayne Whiteman, and I teach mechanical engineering at Georgia Tech.

Earlier in my career,

I served as a professor at the United States Military Academy at West Point.

This course is an advanced study of the dynamics of rigid bodies undergoing

three-dimensional motion.

We'll solve many real world examples of engineering systems that you may

encounter and be responsible for analyzing or even possibly designing.

We'll look at robots like Simon, shown here, or

other robotic applications as they undergo dynamic motion.

We'll make extensive use of a model of the retracting landing gear for

an airplane to demonstrate concepts in the course.

We'll study the motion associated with satellite dish rotations, and

we'll even study the motion of satellites in space.

Cranes have a number of moving parts, and they have interesting,

dynamic characteristics that you will learn about.

Spinning discs and

rotating parts of mechanisms are integral to engineering systems.

Here's a video of a rotating vinyl record that we'll analyze but

the principles used in examining this system will be the same principles used to

study numerous other rotating applications.

You may be curious why hurricanes always rotate in the same direction, or

why a football is thrown about its longest axis.

By the time you complete this course,

you will understand these engineering principles.

The format of the course will be 35 modules,

approximately ten minutes each over a period of six weeks.

There will be a graded quiz each week.

To be successful in the course,

you will need to have mastered basic engineering mechanics concepts and to have

successfully completed my earlier course entitled Engineering Systems in Motion,

the Dynamics of Particles and Bodies in 2D Motion.

We will apply many of the engineering fundamentals learned in that class and

you will need those skills before attempting this course.

As with my previous courses,

my hope is that this course will change the way you look at the world around you.

We will have been successful if this course sparks an interest

in you to explore engineering systems that you encounter on a daily basis and

look at them through the eyes of an engineer.

So, that was the intro video for the course.

Now, let's look at the learning outcomes for the first module.

We're gonna go ahead and first start by describing the relationship of this

engineering dynamics course as part of the overall study of engineering mechanics.

And we're gonna list the major topics that we're gonna cover in the course.

So, as I've said in my earlier courses, engineering mechanics or

what sometimes called engineering science is the bridge between the math and

basic sciences to the mechanical engineering applications.

So, we start with these observations about how the physical world works,

that's captured by scientists, and

then engineers apply those concepts to fulfill human needs.

And so, this is just the schematic of how we like the look,

how I like to look at the breakout of engineering mechanics.

We're studying rigid bodies.

The other courses in mechanics materials will study deformable bodies,

start talking about things like stress and strain.

We're working on rigid bodies, and previous courses looked at statics,

and then an earlier course, a precursor to this course, I looked at

dynamics from a two dimensional sense, or a planar dynamic sense.

Now, we're going to look at full-blown, three-dimensional analysis of dynamics,

and this is an advanced study of dynamics.

And so, we'll break the course, again, into two parts.

The first part will be kinematics, or the geometrical aspects of the motion.

And they relate, they're kinda the space and time relationships that relate,

things like position, velocity, acceleration and time.

And then, we'll move on to the kinetics portion of the course, which

relates to forces and moments acting on a body to the actual motion of that body.

So, here's a syllabus of the course.

Again, we'll start with kinematics.

We'll go back and look at angular velocity and angular acceleration again, but

this time, from a 3D perspective.

We'll also look from a 3D perspective at velocities and

accelerations in moving reference frames.

We'll learn about Eulerian angles that are used to orient bodies in

three-dimensional motion.

And we'll look at rotation matrices for again,

rotating properties within three dimensions as we study dynamic situations.

We'll then move on to kinetics.

We'll look at angular momentum in 3D and

we'll look at the inertial properties of 3D bodies.

Both of those again, we looked at 2D, but I'm gonna extend them to three dimensions.

And then, in the final portion of the course,

we'll do rotational motion of rigid bodies using Euler equations, and

then, we'll apply the impulse-momentum principle to 3D motion and

work-energy principle to 3D motion.

And at that point, you'll be true dynamicist and

able to analyze some very advanced engineering problems.

And so, I look forward to getting started with you in the next module.
