Elevation View
|
✔ An elevation view is an orthographic 2-D drawing of the above-ground portion of a structure.
|
|
|
Shear
|
Shear is a force that results in theh deformation of an object such that the object's parallel planes move past one another.
|
|
|
Truss
|
A truss is a triangular arrangement of structural members.
|
|
|
Decking
|
Panels that make up the flooring of a deck.
|
|
|
Joists
|
Joists are small supporting beams for the decking.
|
|
|
Footings
|
Footings are cement piles in the ground for support of a structure.
|
|
|
Structural Components
|
Components used to build structures that provide support.
|
|
|
Safety Factor
|
The safety factor is the ratio of the maximum stress or load which something can withstand to the stress or load which it was designed to withstand under normal operation.
|
|
|
Failure Analysis
|
The purpose of failure analysis is to identify potential problems before they happen.
|
|
|
Failure Modes
|
Failure modes describe the way an object failed, for example, suddenly or gradually.
|
|
|
Failure Site
|
The failure site is where in the object failure occurred.
|
|
|
Failure Mechanism
|
Failure mechanism is what physically happened in the failure.
|
|
|
Root cause
|
The root cause is the aspect of design, defect, or load that lead to a failure.
|
|
|
Tensile Strength
|
The tensile strength of a material is a measure of how hard something can be pulled apart before it breaks.
|
|
|
Compressive Strength
|
The compressive strength of a material is a measure of how hard something can be pushed together before it is crushed.
|
|
|
Bending Strength
|
Bending strength is a measure of how hard something can be pushed in the center while the two ends are held stationary before it breaks.
|
|
|
Shear Strength
|
The shear strength of a material is a measure of how hard one part of an object can be pushed or pulled one way while another part is pushed or pulled the opposite way, without breaking.
|
|
|
Torsional Strength
|
The torsional strength of a material is a measure of how much twisting force an object can withstand without breaking.
|
|
|
Elastic Materials
|
Elastic materials change their shape when under a load, but return to their original shape when the load is removed.
|
|
|
Plastic Materials
|
Plastic materials change their shape when under a load, but they remain permanently removed when the load is removed.
|
|
|
Brittle Materials
|
Brittle materials break or crumble rather than deform under a load.
|
|
|
Malleable Materials
|
Malleable materials can easily be shaped by hammering or rolling, and they keep their new shape. Some materials can be made more malleable by heating.
|
|
|
Stress
|
Stress is the force (F) applied to a unit area (A) of an object. Stress is measured in force units such as pounds (lbs) divided by area units, such as square inches.
Stress=F/A |
|
|
Strain
|
Strain is the amount that a material deforms due to applied stress. Strain is measured as a change in length divided by the original length of the object.
|
|
|
Aggregate
|
Aggregate is a dry mixture of sand and gravel in which the grains are different sizes.
|
|
|
Cement
|
Cement is the "glue" that holds the aggregate together.
|
|
|
Concrete
|
Concrete is a mixture of cement, water, and aggregate.
|
|
|
Thermal Energy
|
Thermal energy is like a substance but is not a substance. Thermal energy can flow from one place to another. Thermal energy can flow by conduction, radiation, or convection.
|
|
|
Plan View
|
Plan views are drawn as though the ceiling and roof are removed so you can look down at the floor.
|
|
|
Scale Model
|
A scale model is a 3-D structure often made of cardboard or wood.
|
|
|
Geo
|
Earth or land related
|
