The moment of a force with respect to a point is the product of the absolute magnitude of the force and the perpendicular distance of its line of action from the reference point. The distance a is called the lever arm. The unit of the moment is the product of the force and the length.<\/p>\n

The unit of force is the Newton.
One Newton is the force that imparts an acceleration of 1m\/s\u00b2 to the mass 1Kg.
1N = 1Kg m\/s\u00b2<\/p>\n

Forces cannot be perceived directly. They are recognised and measured through their effect.<\/p>\n
To determine forces, you need three pieces of information: the magnitude, the direction and the point of application.
Forces can be determined precisely with:<\/p>\n
The following specifications should be available for the graphical representation:<\/p>\n

The formulas of the counting criterion are for:<\/p>\n

<\/span><\/li>\nLoad assumptions in building construction<\/h3>\n
The basic regulation for load assumptions is DIN 1055, but Eurocode1 is now authoritative according to the new European regulations.
After the load assumption, the load transfer is calculated. In this process, the loads are transferred from the roof slab to the foundations and are used to dimension the foundation sizes and the degree of reinforcement.\u00a0<\/span><\/p>\nSupport<\/h3>\n
These supports are called\u00a0<\/span>monovalent<\/span>\u00a0<\/span>designated.<\/p>\n
These supports are called\u00a0<\/span>Bivalent<\/span>\u00a0<\/span>Designates<\/p>\n
These supports are called\u00a0<\/span>Trivalent<\/span>\u00a0<\/span>designated.<\/p>\n
<\/p>\nForces on components<\/h3>\n
All forces acting on a structure must be in balance with each other.
The acting forces are divided into permanent and live loads.
Permanent loads are the loads of the building structures themselves.
They are designated with G.
Live loads are caused by dead loads from people, vehicles, snow, etc.
They are designated with Q.<\/p>\n
