摘要

力学的发展与人类生产、生活密切相关。在古代虽然没有力学理指导，但古人在生产、生活实践中却广泛地运用了力学原理。从原始钻木取火，石器的尖劈到“炉体常平”的被中香炉；从汲水的尖底陶罐到大型天文仪器（水运仪象台）。精致小巧的器皿，更有大型复杂的机械。随着社会的发展，伟大的物理学家们建立力学理论知识，于是力学知识在我们生活中的应用就越来越广泛。例如千年不倒的桥梁、古塔，宏伟建筑群的建成。我们人类运用惯性定理来区分生鸡蛋和熟鸡蛋，利用悬浮条件来将米中混有的糠谷，石子分开，利用大气压的作用将墨水打入我的笔胆里等等，无不体现力学在我们生活中应用。

力学知识来源于生活，同时服务于生活。力学知识无时无刻不在影响我们的生活，改变我们的生活，随着力学知识在实践中的不断应用，我们的生活发生了翻天覆地的变化。社会各行各业对力学知识的需求不断加大，从而人类迫切需要对力学在生活应用进行研究。

ABSTRACT

The mechanical development and people's production and life are closely related.

In ancient times although no mechanics theory as the guide, but the ancients in

production and life practice it widely used mechanical principle. From the

original bore wood to get fire, the Jian Pi to "furnace chang ping" of incense burner,

Draw water from the pointed bottom terrine to large astronomical instrument (water

meter like table). Delicate small vessels, more large complicated machinery.

With the development of the society, great physicists building mechanics theory

knowledge, and mechanics knowledge application is more and more widely in our life.

In one thousand, for example, Bridges, pagodas and grand buildings were built. We

human inertia theorem are used to distinguish between raw eggs and cooked eggs,

suspension condition is used to mix in rice chaff some valley, stones, separately use

the function of atmospheric pressure will break into my Bi Dan ink and so on, all

reflect mechanical application in our life .

Mechanics knowledge originates from life, and at the same time in the service

life ?Mechanics knowledge all the time not affect our life, change our life, along with

the mechanics knowledge in the practice of continuous application, our life has

undergone earth-shaking changes. The social people from all walks of life to

mechanics knowledge increasing demand, thus human urgent need in the life of the

mechanical application.
