Lesson 1
That branch of scientific analysis which deal with motion,time and forces is called mechanice and is made up of tow parts, statics and dynamics.
For example , if the force operating on a sleeve bering becoes too hign, it will squeeze out the oil film and cause metal-to-metal contact, overheating and rapid failure of the bearing.
Our intuitive conceot of force includes such ideas as place of application , direction , and magnitude, and these are called the characteristies of a foce.
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, i.e. ,incapable of deformation, in order to simplify the analysis.
The rigid-body assumption cannot be used intenal stresses and strin due to the applied forced to be analyzed. Thus we consider the body to be capable of deforming.
If all the forces acting on a particle nare balanced, the particle wi

该分公司的科学分析，处理的议案，时间和力量，是所谓的mechanice ，并成立拖车部分，静力学和动力学。
例如，如果该部队的运作袖白令becoes太hign ，它将排挤油膜和事业的金属-金属接触，过热和快速失败的轴承。
我们的直观conceot武力，包括这种想法，作为地方的应用，方向和规模，这些都是所谓的特性一foce 。
所有机构都是弹性或塑料，并会变形，如果付诸实施的力量，当变形，这些机构是小，他们经常被假定为刚性，即不能变形，在为了简化分析。
该刚体的假设，不能用于intenal强调和strin由于应用被迫进行分析。因此，我们认为，机构能够变形。
如果所有的力量，采取行动，粒子nare平衡，粒子要么留在休息或将继续动议在一条直线，在匀速

1拉伸试验组成slowy拉动的样本材料与拉伸载荷，直至breakss ，两端拉伸标本通常扩大，以提供额外的面积为吸引人，以避免样本打破，而现正陷入。
通常的方式进行测试，是变形的试样在一个恒定的速度，例如，在万能试验机，议案之间的固定和移动crossheads可以控制在一个恒定的速度。
负载必须适用于执行这项位移速率不同，作为测试的收益。这个包袱f可划分由截面积一，以获取强调，在该标本在任何时间测试期间。
但实际测量△ L是最好的地方，这是可行的。应力的基础上，初步（ undeformed ）尺寸，爱和李，都是所谓的工程应力和应变。
韧性和脆性材料的行为不同，在压缩试验以及。压缩测试上进行短圆柱标本放在beween平行板。
压缩测试图retaions这些材料的质量特点的紧张测试图。最终压缩强度一脆性材料是决心在同样的方式在紧张。
