Dead load. The dead load includes loads that are relatively constant over time, including the weight of the structure itself, and immovable fixtures such as walls, plasterboard or carpet. The roof is also a dead load. Dead loads are also known as permanent or static loads. Building materials are not dead loads until constructed in permanent ...
Static load testing is an in situ type of load testing used in geotechnical investigation to determine the bearing capacity of deep foundations prior to the construction of a building. It differs from the statnamic load test and dynamic load testing in that the pressure applied to the pile is slower.

In engineering, a factor of safety (FoS) or safety factor (SF) expresses how much stronger a system is than it needs to be for an intended load.Safety factors are often calculated using detailed analysis because comprehensive testing is impractical on many projects, such as bridges and buildings, but the structure's ability to carry a load must be determined to a reasonable accuracy.
In general, maximum load on a ball bearing is proportional to outer diameter of the bearing times the width of the bearing (where width is measured in direction of axle). [7] Bearings have static load ratings. These are based on not exceeding a certain amount of plastic deformation in the raceway.
The L10/B10 life of the bearing is theoretical, and may not represent service life of the bearing. Bearings are also rated using the C 0 (static loading) value. This is the basic load rating as a reference, and not an actual load value. For plain bearings, some materials give a much longer life than others.
Mechanical load is the physical stress on a mechanical system or component [1] leading to strain. Loads can be static or dynamic. Some loads are specified as part of the design criteria of a mechanical system. Depending on the usage, some mechanical loads can be measured by an appropriate test method in a laboratory or in the field.
Overload: Within its rating, the load cell deforms elastically and returns to its shape after being unloaded. If subjected to loads above its maximum rating, the material of the load cell may plastically deform ; this may result in a signal offset, loss of linearity, difficulty with or impossibility of calibration, or even mechanical damage to ...
