The course of Theoretical Mechanisc includes three parts: Statics, Kinematics

And Dynamics. The first part, Statics, introduces basic concepts and principles of statics, the free-body diagrams, basic operation with force systems，reduction  and resultants of force systems，equilibrium of planar force systems，equilibrium of spatial force systems and friction. The second part, Kinematics, covers kinematics of a point, translation and rotation of rigid bodies，composite motion of a point and plane motion of rigid bodies. The third part, Dynamics, covers kinetics of a particle,  principle of linear impulse and momentum，principle of angular impulse and momentum，principle of work and kinetic energy，collision, D' Alembert' s principle，and principle of virtual displacements.

Theoretical Mechanics is a branch of solid mechanics, which provides a basic understanding of the part of mechanics which deals with the equilibrium and accelerated motion of bodies under the action of forces. It lays the foundation and framework for subsequent advanced mechanics courses, such as Mechanics of Materials. The course covers the contents of three parts:

-statics includes the free-body-diagram, planar force systems, spatial force systems, friction, etc.

-kinematics includes the kinematics of a particle, the simple motions of a rigid body, resultant motion of a particle, planar motion of a rigid body, etc.

-kinetics includes the particle dynamics, theorems of linear momentum, angular momentum and kinetic energy of particle systems, D’ Alembert’ s principle, principle of virtual displacement, etc.

The goal of this course is to help students develop a comprehensive understanding of the basic principles of mechanics so that they can apply them to real situations and deal with mechanics problems in engineering.
