Magnitude is how forces are measured, seeing as a force with a high magnitude is a powerful force, and one with a low magnitude is a weak force. Magnitude is also shown by how long an arrow is in diagrams.
The direction of force is simply the way that the force is pushing, pulling, twisting or shearing
A dead load is a constant load on a structure
A live load is a moving, variable weight added to the already existing weight of a structure
Compression
Compression is the action or state of being squished down or made smaller or more pressed together.
Torsion
Torsion is the twisting of an object due to an applied force
Tension
Tension is the pulling force exerted by each end of a string, cable, chain, or similar one-dimensional continuous object, or by each end of a rod or similar three dimensional object.
Shear
Shear is a map of a coordinate space in which one coordinate is held fixed and the other coordinate or coordinates are shifted.
The center of gravity is the place in a system or body where the weight is evenly dispersed and all sides are in balance.
Stability is the state of being resistant to change or, just the state of being stable.
A framed structure in any material is one that is made stable by a skeleton that is able to stand by itself as a rigid structure without depending on floors or walls to resist deformation.
Structures, which keep their shape and support loads, even without a frame, or solid mass material inside, are called shell structures. These structures use a thin, carefully shaped, outer layer of material, to provide their strength and rigidity. The shape of a shell structure spreads forces throughout the whole structure, which means every part of the structure supports only a small part of the load, giving it its strength.
Subtopic
Can be made by piling up or forming similar materials into a particular shape or design. Mass structures also are not always solid, but are layered and have hollowed out areas for specific functions, such as as dams, walls or maybe monuments
