Introduction

Mechanical motion,
Any change in the relative positions of material
bodies in space which occurs in the course of
time,
1,The object of theoretical mechanics
Theoretical Mechanics,
The science of the general laws of mechanical
motions of material bodies,

1) Theoretical mechanics is a technical basic course with
intensive use of mathematical methods,
2,The task and content of theoretical mechanics
2) Theoretical mechanics is the important foundation of many
such as,material mechanics,mechanical theory,
mechanical components,structural mechanics,elasticity
theory,fluid mechanics,mechanical oscillations,etc,

1,理论力学是一门理论性较强的技术基础课

2,理论力学是很多专业课程的重要基础

Statics,
Kinematics,
Dynamics,
Studies the laws of equilibria of material bodies
subjected to the action of forces,the general character
of forces and the methods to simplify force systems,
Deals with the general geometrical description of the
motions of bodies,does not study the reasons of their
motions,
Studies the laws of motion of material bodies under
the action of forces,
3) The content of theoretical mechanics

3,The basic logical concepts in theoretical mechanics
Theoretical mechanics starts with practical tasks,Some
principles then are found by abstraction,synthesis and
induction,Using mathematical deduction and logic inference,
some theorems and conclusions are obtained making up a
theoretical system,Finally,the validity of the theory is validated
by experiments,

The foundation of statics is given by the works of Archimedes
(ancient Greek,287~212 B.C.),
Vinci (Italian,1452~1519) studied the friction of motion,statics and
force moments,
Copernicus (Polish astronomer,1473~1543) founded the universal
heliocentric theory,
Kepler (German,1571~1630) discovered the three laws of the
motion of planets,
Galilei (Italian,1564~1642) founded the law of a free falling body,
of inertia and defined the concept of acceleration,
4,A brief history of theoretical mechanics

The great English scientist Newton(1643~1727) published the book
Mathematical Principles of Natural Philosophy in 1687,It sums up
all his studies and brings forward the three fundamental laws of
mechanics,the law of universal gravitation and the laws at celestial
mechanics,He is the founder of mechanics,
Bernoulli (Swiss,1667~1748) found the principle of virtual
displacements,
Euler (Swiss,1707~1783) published the book Mechanics which used
differential equations to study mechanics,
D’Alembert (French,1717~1785) evolved d’Alembert’s principle,
Lagrange (French,1736~1813) brought forward the lagrange equations
of the second kind,

5,Methods of modern teaching of theoretical mechanics
CAI (Computer-aided instruction.) teaching,
multimedia teaching,etc,

CAI教学，多媒体教学等。
