This course is mainly for students who have selected the field of mechanical engineering (Department of Mechanical Engineering) and lectures on the following points as an introductory course to various applied mechanics in the field.
1. Statics (mass point, rigid body, moment of a force, etc.)
2. Dynamics of a mass point (relative motion, Coriolis acceleration, etc.)
3. Dynamics of a rigid body (moment of inertia, angular momentum, tensor of inertia, gyroscopic effect, etc.)
The notable aim of this course is to reinforce the understanding gained in Fundamentals of Mechanics, a first-year general education course, and for students to gain ability in solving specific mechanics problems in theory and by numerical calculation as students of mechanical engineering for whom mechanics is especially vital.
1. Statics: To understand force and moment that works on a point mass or rigid body.
2. Dynamics1: To understand relative motion, relative and Coriolis acceleration.
3. Dynamics2: To understancd inertia moment of a rigid body.
4. Dynamics3: To introduce Euler's formula of dynamics based on angular momentum and inertia tensor. And to understand gyro effect.
This class aims at learning of 1 in learning objective.
