Teaching Method

Outline:

Every machine is composed of a combination of mechanical elements and parts. Machine designers should know the types and characteristics of machine elements. In this course students will learn how to design gears and shafts through the design of gear systems.

Style:

Listen to the explanation on some examples, then deepen their understanding through exercises.

Notice:

Pay attention to machine elements in the machines used in your everyday life, and understand the intentions that are adopted by them.
Can take makeup exam in need aid up to maximum of 60 points.
