Ch. 1  

Review the "Introduction" page on this site, then review the first chapter of your textbook. This chapter is complimentary to the web-based “Introduction”. Do not be concerned about the equations that appear in this chapter. Try to understand the concepts of multibody systems and dynamics and different ways to formulate a problem.

Ch. 2 Lesson 2.pdf

There are slight differences in the notations between the textbook and the PDF notes. We will follow the notation from the Notes. This is the most important lesson in this course. It provides you with the analytical tools, the notation, or simply "the language" that you need for multibody dynamics. By following the notation described in this lesson, you will eventually find that multibody formulations to be simple and easy to manipulate. The use of this notation is a requirement in this course. If your assignemnt is prepared using a different notation, you may loose either partial or full credit for that assignment.

Sections 8.1, 8.2 Lesson 5.pdf

Kinematics and dynamics (kinetics) of multi-particle systems are presented in these notes. The form and the derivation of equations of motion for particles are much simpler than those for rigid bodies. Therefore, understanding how the multi-particle equations are derived (and eventually solved numerically) will prepare us for the multibody equations that are more complicated. You should be able to follow the derivation of most of the material in these notes: kinematics of unconstrained and constrained multi-particle syetms, and dynamics of unconstrained multi-particle systems. However, if you are not familiar with the use of Lagrange multiplier techique, you may not understand how the equations of motion are derived for constrained multi-particle systems. This will be discussed in the class and later on in more detail when we deal with constrained multi-body systems.

Section 4.1 Lesson 6.pdf

This lesson provides an overview of the kinematics of a rigid body in planar motion. This material serves as an introduction to the kinematics of a body in 3D space.

7
 Section 6.1 Lesson 7.pdf

Kinematics of a rigid body in 3D space is introduced in this lesson. Since rotation in space is analytically more complicated than the planar motion, the following several lessons are dedicated to that topic only. It is very important to comprehend analytical and physical aspects of 3D rotation.

 Sections 6.1.1, 6.1.2, Appendix A Lesson 8-A.pdf Lesson 8-B.pdf

This lesson introduces you to the most commonly used (not necessarily the best!) rotational coordinates in space--Euler angles and one of its conventions known as Bryant angles.

9
Sections 6.1.1, 6.1.2, 6.1.3, 6.1.4, 6.1.5, 6.2, 6.2.1 and Appendix B. Lesson 9.pdf This lesson introduces you to a set of rotational coordinates in space known as Euler parameters (also known as quaternions). This lesson provides you with one of the most important tools for spatial kinematics.
10
Sections 6.3, 6.3.1, A.1.1 and A.2.1. Lesson 10.pdf This lesson introduces you to the vectors of angular velocity and acceleration. You will learn about the relationships between these vectors and the first and second time derivatives of Euler parameters (and Euler angles).

Lesson 11-A.pdf Lesson 11-B.pdf Lesson 11-C.pdf Lesson 11-D.pdf

This lesson introduces you to the kinematic constraints in Body Coordinate Formulation (also called Cartesian or absolue coordinate foirmulations).
