第一单元 应力与应变

That branch of scientific analysis which motions, times and forces is called mechanics

and is made up of two parts, statics and dynamics.

研究位移、时间和力运动乘力是科学分析法的一个分歧，被称作力学，力学由两大部

分组成，静力学和动力学。

For example, if the force operating on a sleeve bearing becomes too high, it will squeeze out the oil film and cause metal-to-metal contact, overheating and rapid failure of the bearing.

例如：如果止推轴承上的作用力过大的话，会挤出油膜，引起金属和金属之间的相互接触，轴承将过热而迅速失效。

Our intuitive concept of force includes such ideas as place of application, direction, and magnitude, and these are called the characteristics of a force.

力的直观概念包括力的作用点、大小、方向，这些被称为力的三要素。

All bodies are either elastic or plastic and will be deformed if acted upon by forces. When the deformation of such bodies is small, they are frequently assumed to be rigid,
