课程概述

Engineering Mechanics is a theoretical fundamental course for engineering specialties. This course is to provide a clear and thorough presentation of the theory and application of engineering mechanics. It has the following features:

1)       Present the concepts, principles and the illustrative examples in a logical and orderly manner. Often the typical example problems include several solutions or give the clues of several solutions. The relationship between various principles is thoroughly analyzed and how to choose the best principle for solving a given problem is discussed.

2)       Continuously emphasize the importance of communicating solutions through diagrams, including free-body diagram, kinematic diagram, kinetic diagram and the impulse and momentum diagram.

It is hoped that the course can help build students’ strong conceptual understanding of the basic principles and develop the ability to apply these principles for successfully solving mechanics problems.


授课目标

1.      Let students have the knowledge of creating idealized models, drawing free-body diagrams, applying equations of equilibrium or equations of motion for a particle, a system of particles, a rigid body and a system of rigid bodies. Understand the basic principles of analysis and designs of structural members.

2.  Master the fundamental concepts and calculations which will be widely used in the further study of other courses of mechanics and professional courses.

3.  Improve the students’ professional abilities through the training of problem-solving.

4.  Promote the students’ capacity of all aspects, including creativity, communication ability, cooperating spirits, leadership, etc.
