就是和一个平面垂直的力。Normal force翻译过来是正向力，你也可以叫它支持力。但是支持力可能不是单方向，其中和平面垂直的component才是normal force."In mechanics, the normal force Fn is the component, perpendicular to the surface of contact, of the contact force exerted on an object by,...
The normal force is the counter force to a mass pushing against a surface. The normal force is always perpendicular to the surface. When solving problems involving normal forces, it's important to draw a free body diagram, including all of the forces acting on the mass. All of the forces...

What is normal force? Normal force is the perpendicular force that the surface exerts on an object. For example, if you put a book on a table, there is a gravitational force that is pulling it toward the ground. To counteract this force, the table exerts a force on the book, preventing...
The spring assembly (42) has a spring constant in the direction (Z) which is perpendicular to the surface (5) of the body (10), being less than 5% of the ratio between the normal force (N) and the average height uncertainty of the surface is the body (10). The force application ...
This study aims to analyze the effect of hand posture and surface orientation on hand force while pressing a flat surface. Twelve participants, 6 females and 6 males ages 19-25, performed three exertions (100%, 30% and 10% MVC- Maximum Voluntary Contraction) perpendicular to a plate in 4...
So the weight force points down. This is W equals m*g. And then we don't have any applied forces or tensions or anything like that, but we do have 2 surfaces in contact, unlike how we did in the first example. So we do have a normal force that points perpendicular to the surf...
2. Shear Stress 切应力 In Fig.1.8 the applied force was normal, that is perpendicular to the cross section.Fig.1.9 (a) represents a section in which the internal load is not normal. In Fig.1.9(b) this force P, a vector, has been resolved into a normal component Py can be related ...
In this video, we will learn how to analyze weight, friction, and normal reaction forces contributing to the motion of objects on sloped surfaces.
