Load

live load and dead load are also called Static Load.

Live load: The live load is also ceused by gravity, but it can vary.

Dynamic Load

Dynamic loads is loads happens outside of the structure.Dynamic load s a force that can change acting on a structure.Eg.snow, wind and rain.

Dead load: The dead load is caused by the force of gravity acting on the structure itself.

Solid Structures-an object that uses solid construction to support.

Shell Structures-a hollow structure with a curved shape providing high strength and rigidity.

Solid Structure-an object that uses solid construction to support loads.

Frame Structure-a network of parts that supprots loads.

Function-the task or purpose of a structure.

Form-the shape and physical appearance of a structure.

Combination Structures-they have solid, shell, and frame parts.

External force-a forse acting on an object or structure from the outside.

Internal force-force acting between two parts of body.

Tension-an internal force pulling the particles of an objevt apart.

Force

Compression is an internal force that presses or squeezes the particles of an object together.

Torsion is internal twisting forces created in an object as a result of a twisting motion being applied to the object.

Shear force acting in an object as a result of pushes and/or pulls in opposite directions; usually results in rips or tears in an object.
