Forces
This load is the weight of an object by itself with only the force of gravity and the weight of the materials it is made from acting on it.
What is a static load?
This is the force pulling objects toward the Earth.
What is gravity?
This support is used as horizontal bracing for a bridge and are made into the shape of a triangle.
What is a truss?
An example of this kind of structure is a beaver dam.
What is a natural structure?
This load is when the weight of an object or objects is added to a structure.
What is a dynamic load?
This is described as a push or a pull.
What is a force.
This support is a long piece of wood, concrete, or steel that supports the roadway of a bridge or the ceiling of a building.
What is a beam?
A balloon is this type of structure.
What is a shell structure?
This load affects a structure when it shakes it back and forth violently as the ground moves.
What is an earthquake load?
This is an imaginary point around which the weight of an object is evenly distributed.
What is centre of gravity?
This support comes in the shape of bars that connect to give support or strength to a structure through compression.
What is a strut or tie?
A tent is this kind of structure.
What is a frame structure?
This load is when wind blows on an object.
What is a wind load?
This happens when the centre of gravity is not over the base.
What is an unstable structure?
This support is a set of flexible steel ropes that support the roadway of a suspension bridge.
What are cables?
This kind of structure is built by piling material together.
What is a sandcastle?
This force can be described as a "tearing" or cutting force where one side goes past the other.
What is shear?
This load is created when an object moves on a structure.
What is a dynamic load?
This can improve the stability of a structure.
What is making the base wider or lowering the centre of gravity?
This method of strengthening materials involves layering and often gluing.
What is lamination?
This kind of structure can also be called "manufactures".
What is a human-made structure?
