[3] [4] [5] There are several different types of "hose loads" in use, which is the way the hose is folded in the lay: Accordion load – The hose is loaded so that when it is flat, it is standing on end. The finished load resembles an accordion. Flat load – The flat hose is simply placed in the track so that it is stacked.
A preconnected attack line that is typically 1¾" diameter, and stored either on the front bumper of the apparatus or in an exterior (exposed) side well. Trash lines are typically shorter length than cross-lays , and are intended for use against dumpster fires, etc., where a longer length of hose (and consequent rebedding after the suppression ...
Shoulder load: The amount of hose a single firefighter can pull off a hose wagon or pumper truck and carry toward the fire. Sides A, B, C, and D : Terms used by firefighters labeling the multiple sides of a building starting with side A or Alpha being the front of the structure and working its way around the outside of the structure in a ...
The most common usage is to describe the load applied to a fastener as a result of its being installed, i.e., before any external loads are applied (e.g., tightening the nut on a bolt). Preload in such cases is important for several reasons.
A load case is a combination of different types of loads with safety factors applied to them. A structure is checked for strength and serviceability against all the load cases it is likely to experience during its lifetime. Typical load cases for design for strength (ultimate load cases; ULS) are: 1.2 x Dead Load + 1.6 x Live Load
Consumer loads expect voltage within a certain range, and the regulators require it be within a certain percent of the nominal voltage (for example, in the US it is ±5%). Reactive power can be used to compensate the voltage drops, but must be provided closer to the loads than real power needs (this is because reactive power tend to travel ...

All mission-essential equipment on board naval ships and submarines must be qualified for shock loads caused by underwater explosions. The dynamic design analysis method (DDAM) is a US Navy-developed analytical procedure for evaluating the design of equipment subject to dynamic loading caused by underwater explosions (UNDEX).
