The rolling motion towards a steady state (or list) angle due to the ship's own weight distribution is referred in marine engineering as list. List normally refers to an unintentional or unexpected offset, as caused by flooding, battle damage, shifting cargo, etc.
The avoirdupois weight system is thought to have come into use in England around 1300. [citation needed] It was originally used for weighing wool. In the early 14th century several other specialized weight systems were used, including the weight system of the Hanseatic League with a 16-ounce pound of 7200 grains and an 8-ounce mark.
RP7 - Mass Properties Management and Control of Military Aircraft: This class will familiarize students with effective control of the weight and other mass properties of an aircraft. The class will also expose students to other considerations associated with mass properties management and control described in SAWE RP-07.
An overview of ranges of mass. To help compare different orders of magnitude, the following lists describe various mass levels between 10 −67 kg and 10 52 kg. The least massive thing listed here is a graviton, and the most massive thing is the observable universe.
The technical or gravitational FPS system [6] or British gravitational system is a coherent variant of the FPS system that is most common among engineers in the United States. It takes the pound-force as a fundamental unit of force instead of the pound as a fundamental unit of mass. In this sub-system, the unit of mass is a derived unit known ...
The slug is a derived unit of mass in a weight-based system of measures, most notably within the British Imperial measurement system and the United States customary measures system. Systems of measure either define mass and derive a force unit or define a base force and derive a mass unit [ 1 ] (cf. poundal , a derived unit of force in a mass ...
Instability during weight-shifting activities or the inability to perform certain weight transfer tasks, such as bending forward to take objects from a shelf or leaning backward to rinse hair in the shower, can result from a restricted LoS boundary. The ability to voluntarily move the COG to positions within the Limits of Stability (LOS) with ...
The avoirdupois units of mass and weight differ for units larger than a pound (lb). The British imperial system uses a stone of 14 lb, a long hundredweight of 112 lb and a long ton of 2,240 lb. The stone is not a measurement of weight used in the US. The US customary system uses the short hundredweight of 100 lb and short ton of 2,000 lb.
