Course description and aims

This course gives knowledge and skills of the rigid body dynamics including the motion of point mass observed from moving coordinates and the motion of rigid body, mainly for the students who are learning the transdisciplinary science and engineering.
The aim is to let the students to understand the logic of the dynamics of the rigid body and to learn the skills for applications, based on the basic dynamics learnt in the lectures of the first year. Because recent engineering and technology are not limited in a discipline, the understanding of them will be helpful for global engineers, who will develop the future of the world and need wide-ranged knowledge and skills to solve complicated problems.

Student learning outcomes

Out-comes are the knowledge and the skills
1) To derive the equation of motion of point mass observed from moving coordinate and to utilize it for applications.
2) To explain the mechanism of the centrifugal force and the Coliori’s force
3) To derive the equation of motion of rotating rigid body and to utilize it for applications
4) To derive the equation of motion of rotating rigid body observed from moving coordinates and to utilize it for applications

Keywords
