Workbench对面施加pressure 和force是等效的
Workbench对面施加pressure 和force是等效的引言：初学Workbench，对一个面施加载荷时，不知道是施加force还是pressure，因为force是集中力，单位为N；而pressure是压强，单位为Pa。笔者用workbench做了一次试验，对一个面先施加pressure，计算出应力云图。再将pressure乘以以受力面积将压强换算成force，重新计算应力云图。结论：Workbench对面施加pressure 和force是等效的，也就是force自动会被换算成均布的pressure。
实验过程如下：
试验1：一个悬臂梁，在自由端的一个平面施加1MPa的pressure，如图1，
图1 对悬臂梁施加pressure
计算出的应力云图如图2；
图2 对悬臂梁施加pressure的应力云图
试验2：一个悬臂梁，在自由端的一个平面施加100N的force，如图3，
图3 对悬臂梁施加force
计算出应力云图，如图4，
图4 对悬臂梁施加force的应力云图
结论：对一个面施加force和pressure计算出的应力云图是相同的，也就是系统将force 自动转换为均布的pressure。

口语对话
Discuss the generation gap A: hi. B: hi, why are you so sleepy now. A: I slept very late last night. B: what did you do? Why you slept so late. A: I was chatting with my grandma on QQ. B: really? So faddish is your grandma. A: not really. This summer I left my hometown to attend college, she said she would miss me very much, then I told her that we can talk with each other on line. B: then you taught her how to use QQ? A: before that I taught her pinyin and surfing the internet. B: you really a patient girl, aren’t you? A: the first time I chatted with grandma, I thought more than that, I was proud of myself, but now I really regretted what I had done. B: why? Isn’t it interesting to chat with your family? A: you know, we have different background, when I referred to many things, I had to explain to her in detail, what I did in the most of time I spend on talking with her is explaining, it’s boring. B: the feeling is mutual, I ever told my mother the word “diaosi”, then she kept asking me what is that, I tried my best to make it clear, after a very long time, I suddenly realized that all I did is in vain. A: maybe this is what is called generation gap. There is always some troubles for both of us to communicate with each other. B: and what’s more, they always want to make clear what we are doing. Sometimes we are glad to tell them, just to find that they don’t understand at all. What’s worse, we don’t like to be controlled by others, we cry for freedom. Maybe that is why we often quarrel with our family. A: and they define us as treason. B: yes, that is what I can’t accept, we live in different condition, we just have some characteristics to suit to this condition. They always define all we have that is different from them as bad thing, and try to write them off. A: don’t be so pessimistic, they just want to show their concern for us, they both want to make us better. Pay more consideration for each other, the situation will improve. B: I hope so.
