Science Assignment

Forces acting on structures are critical in understanding their stability and design. The point where a force hits is known as the point of application, while the imaginary line through which the force passes is the plane of application.

Form & Function

Magnitude and Direction of Force

Magnitude

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.

Direction of Force

The direction of force is simply the way that the force is pushing, pulling, twisting or shearing

Point and Plane of Application of Force

Where forces are hitting a structure is called the point of application, and the imaginary line the force is passing through is called the plane of application.

Design Features

Design features are things in the design of structures that make it stronger, more durable, or to make it look better.

External & Internal Forces

External Forces
Dead Load

A dead load is a constant load on a structure

Live Load

A live load is a moving, variable weight added to the already existing weight of a structure

Internal Forces
Types

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.

Center of Gravity & Stability

Center of Gravity

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

Stability is the state of being resistant to change or, just the state of being stable.

Types of Structures

Frame Structures

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.

Shell Structures

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.

Mass Structures
Facts

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
