Teaching Method

Outline:

Lectures by the instructor.

Style:

Students are required to take notes of the contents on the white board in the class.
A sheet of printed learning materials is distributed in every class. The object is clearly shown on the material. Some exercises, related to the lecture, will also be printed. Students are required to submit the answer before the deadline as homework.
The answer is evaluated and discussed in the beginning of the following class for review.

Notice:

Required subject (training institution of ship officer) for licensed mariner of 3rd grade (engine)
3. Subjects related to engine (No.3)
3. Mechanics and fluid dynamics
(3) Kinds of stress generated in materials and relation between stress and strain

The recognition of credit requires 60 points or more rating.
If obtained evaluation points are less than 60, the student can take an additional exam upon request. The final point is 60, if the student is permitted to acquire the credit by the result of the additional exam.
