Teaching Method

Outline:

In this course, you will learn about mechanical design techniques associated with basic theory learned in industrial mechanics, mechanics of materials, strength and fracture of materials.

Style:

For the purpose of understanding the mechanical design techniques, lectures and exercises will facilitate the learning of principles and examples.

Notice:

You have to attend classes after reviewing industrial mechanics and mechanics of materials. You need to bring your scientific calculator, because we may issue calculations during class.
