All free vidoes are part of the course, but are also provided as samples so you can evaulate the course.

The preliminary video (first video) will provide general information about the course.

The complete Chapter 1 and 2 vidoes are also free and correspond to the book's free sample excerpt.

There are two other free videos, which cover special topics. They are part of the course, but also cover some additional information not directly addressed in the book. They are provided for free to compliment the book and as a service to the composites community.
