Dynamic line rating (DLR), also known as real-time thermal rating (RTTR), is an electric power transmission operation philosophy aiming at maximizing load, when environmental conditions allow it, without compromising safety.
Front-end loading (FEL), also referred to as Front-End Engineering Design (FEED), Front End Planning (FEP), pre-project planning (PPP), and early project planning, is the process for conceptual development of projects in processing industries such as upstream oil and gas, petrochemical, natural gas refining, extractive metallurgy, waste-to-energy, biotechnology, and pharmaceuticals.
A clear distinction is made between the ultimate state (US) and the ultimate limit state (ULS). The Ultimate State is a physical situation that involves either excessive deformations sufficient to cause collapse of the component under consideration or the structure as a whole, or deformations exceeding values considered to be the acceptable tolerance.
Reach truck handling stretch wrapped unit load Air cargo container of the AKH type on a trailer. The term unit load refers to the size of an assemblage into which a number of individual items are combined for ease of storage and handling, [1] for example a pallet load represents a unit load which can be moved easily with a pallet jack or forklift truck, or a container load represents a unit ...
The design load is either the same as or a multiple of the rated load, which represents the system's declared performance capacity, see structural design load section below. Structures and pressure vessels have design loads of the first type. Electric motors, compressors and heaters have design loads of the second type.
E = λh is the normalised ingress load (offered traffic stated in erlang). Note: The erlang is a dimensionless load unit calculated as the mean arrival rate, λ, multiplied by the mean call holding time, h. See Little's law to prove that the erlang unit has to be dimensionless for Little's Law to be dimensionally sane.

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.
