在上年度物理高考复习中 ,上海 (部分 )地区曾出现两类“气流中物体的受力”问题 ,涉及到风的压强和风压两个不同的概念 .笔者根据“工程流体力学”的理论 ,在此谈一下自己粗浅的看法 .图 1例 1 .密度为 ρ、边长为l的匀质的表面光滑的立方体 ,静止在水平面上 ,并抵住一个小木? In the last year’s physics college entrance examination review, there were two types of “forces in the airstream” problem in Shanghai (partial) regions, involving two different concepts of wind pressure and wind pressure. According to the theory of “engineering fluid mechanics”, Here to talk about their superficial views. Figure 1 Example 1. A homogeneous smooth surface cube with density ρ and side length l, resting on a horizontal surface, and resting against a small wood?
