Teaching Method

Outline:

General or Specialized : General
Field of learning : Natural Sciences Common and Basic
Foundational academic disciplines : Engineering / Mechanical Engineering

Relationship with Educational Objectives :
This class is equivalent to "(2) Acquire basic science and technical knowledge".

Relationship with JABEE programs :
The main goal of learning / education in this class is "(A)" is involved.

Course outline :
Industrial dynamics is a subject mainly about aplication of basic dynamics. Though student learn a little about law and principle of dynamics, it is difficult for them. In this subject static dynamics(balance of force) is explained about method of analyzing of engineering phenomena.

Style:

Course method :
The subject is mainly conducted by writing on the blackboard.
Grade evaluation method :
Regular exams (70%) + Mini tests・Practice・Report (30%).
Retaking exams will be carried out for the students who get under 60% in total score.
The retaken exams are equivalent to the term exam. Students can use writing materials and calculator.

Notice:

Precautions on the enrollment :
Students must take this class(no more than one-third of the required number of class hours may be missed) .

Course advice :
This subject is based on Physics and Mathematics, and basic level Physics and Mathematics are very important.
As preparatory study to be done in advance, review the contents of Physics I and Physics II, which are the basic subjects.

Foundational subjects : Physics I (1st year), Physics II (2nd)
Related subjects : Mechanics I, III (3rd year)

Attendance advice :
This subject is one of the basic subjects of integrated engineering. The students are advised to solve the problems in textbooks of dynamics. You should prepare and review continually.
Reports should be submitted by the deadline.
Arriving (leaving) more than 20 minutes late (early) result in one absence, and arriving (leaving) more than 65 minutes late (early) result in two absences.
