Course description and aims

This course focuses on the fundamental kinematics and kinetics to analyze various physical systems, such as mechanical systems. Topics include static mechanics of a point mass, kinetics of a point mass, mechanical work, momentum, mechanical energy, relative motion, moment of inertia, angular momentum, inertia tensor. The basic knowledge for these topics is explained.
It is indispensable to learn kinematics and kinetics for analyses in order to design various physical systems, such as mechanical systems. This course provides their basics which are applied to various mechanical design, such as robotics.

Student learning outcomes

By the end of this course, students will be able to:
1) Use the kinematics for analyses of various physical systems, such as mechanical systems.
1) Use the kinetics for analyses of various physical systems, such as mechanical systems.

Keywords

static mechanics of a point mass, kinetics of a point mass, mechanical work, momentum, mechanical energy, relative motion, moment of inertia, angular momentum, inertia tensor

Competencies that will be developed

✔ Specialist skills Intercultural skills Communication skills Critical thinking skills ✔ Practical and/or problem-solving skills

Class flow

At the beginning of each class, solutions to exercise problems that were assigned during the previous class arereviewed. Towards the end of class, students are given exercise problems related to the lecture given that day to solve.To prepare for class, students should read the course schedule section and check what topics will be covered.Required learning should be completed outside of the classroom for preparation and review purposes.

Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
