Normal Force
Si system, the normal force in newtons (N ) is a mechanical quantity. The concept of the normal force is needed to determine the strength of the materials, to find out the cross-sectional tension level. In connection with the normal friction force, it is the component, perpendicular to the surface (surface being a plane) of contact, of the contact force exerted on an object by, for example, the surface of a floor or wall, preventing the object to fall.
Of the different load types, the following types generates the so-called nominal force
1. Pulling, where the force resistance demands pulling strength of the material.
- normal force, perpendicular force against the reviewed surface
- the pulled body may be long, the cross-sectional stress level determines the force
- the force gets the nominal value of 1
2. Compressing, where the force resistance demands compressing strength of the material. - normal force, perpendicular force against the reviewed surface
- the rod is short enough, the tension level determines the amount of force
- the rod is long enough, buckling determines the amount of force
- the force gets the nominal value of 1
3. Bending, where the force resistance demands bending strength of the material.
- normal force, perpendicular force against the reviewed surface
- the cross-sectional stress level determines the force
- the force gets the nominal value of 1
