Also Abrams' water-cement ratio law. A law which states that the strength of a concrete mix is inversely related to the mass ratio of water to cement. As the water content increases, the strength of the concrete decreases. abrasion The process of scuffing, scratching, wearing down, marring, or rubbing away a substance or substrate. It can be intentionally imposed in a controlled process using ...
ASD load combinations are compared to the ultimate strength reduced by a factor (omega) which provides a mathematical form similar to Allowable Stress Design resolved with a safety factor. This AISC Allowable Strength Design does not attempt to relate capacity to elastic stress levels.
Please see Glossary of engineering for a broad overview of the major concepts of engineering. Most of the terms listed in glossaries are already defined and explained within itself. However, glossaries like this one are useful for looking up, comparing and reviewing large numbers of terms together. You can help enhance this page by adding new ...

Many corporations have such standards, which define some terms and symbols specific to them; on the national and international level, ASME standard Y14.38 [1] is one of the standards. Australia utilises the Technical Drawing standards AS1100.101 (General Principals), AS1100-201 (Mechanical Engineering Drawing) and AS1100-301 (Structural ...
Permissible stress design is a design philosophy used by mechanical engineers and civil engineers. [1] [2] The civil designer ensures that the stresses developed in a structure due to service loads do not exceed the elastic limit. This limit is usually determined by ensuring that stresses remain within the limits through the use of factors of ...
A new definition, in terms of the elementary charge, will take effect on 20 May 2019. [141] The new definition defines the elementary charge (the charge of the proton) as exactly 1.602 176 634 × 10 −19 coulombs. This would implicitly define the coulomb as 1 ⁄ 0.160 217 6634 × 10 18 elementary charges. Coulomb's law
The Civil Engineering Database [1] (CEDB) was created in 1994, and is maintained by American Society of Civil Engineers (ASCE). It is a free bibliographic database, containing 270,000-entries, for all ASCE publications including journals, conference proceedings, books, standards, manuals, magazines, and newspapers on all the disciplines of civil engineering.
