Industrial Mechanics･Dynamics
Course description
In manufacturing, we have to take responsibility for our production. Therefore, in order to achieve unbreakable and "safe and secure" manufacturing, it is necessary to grasp and understand quantitatively the forces and moments acting on objects. In this course, we aim to learn about dynamics, specifically, dynamics of quality points, dynamics of quality point systems, and motion and dynamics of rigid bodies. In particular, students will learn about momentum and force products, work, conservation laws, and the treatment of parallel and rotational motions. Students will also learn about vibrations in one degree of freedom.
Purpose of class
The aim of this course is to give students an idea of the dynamics of quality points. The specific objectives are as follows
1. to be able to formulate and solve equations of motion of quality points and to understand their meaning
2. to be able to calculate mechanical quantities for translational and rotational motions and to explain these motions.
3. To be able to model vibrations and to explain their motion.
Goals and objectives
1. To calculate the decomposition and composition of forces and moments in terms of vectors.
2. To determine the forces and moments occurring in a component.
3. To find the figure centre and centre of gravity of an object.
4. To understand the motion of a quality point (translational and rotational) and to evaluate it quantitatively.
5. To understand the motion of vibrations and to explain the meaning of natural frequencies.

Evaluation method and criteria
There will be two reports (worth 20 points), a mid-term examination (worth 40 points) and a final examination (worth 40 points), for a total of 100 points. The report will be divided into two parts.
Out of a maximum of 100 points, 60 points will be considered a pass. The criteria for the level of passing is the ability to calculate the basic quantities of force and moment and to understand their meaning. Students should be able to calculate quantities of motion of a quality point, formulate equations of motion of a quality point, evaluate translational motion, rotational motion, energy, conservation laws, and calculate quantities.
