righting arm Explanation: Hieronder volgen enige definities die gebruikt worden in stabiliteit. De Engelstalige definities verschillen iets van de Nederlandtalige, maar worden internationaal meer gebruikt. (...) NL Stabiliteitsarm, richtende arm of arm van statische stabiliteit (afkorting: GZ) EN Righting arm (afkorting: GZ) https://nl.wikipedia.org/wiki/Scheepsstabiliteit Righting arm The metacentric height is an approximation for the vessel stability at a small angle (0 15 degrees) of heel. Beyond that range, the stability of the vessel is dominated by what is known as a righting moment. Depending on the geometry of the hull, Naval Architects must iteratively calculate the center of buoyancy at increasing angles of heel. They then calculate the righting moment at this angle, which is determined using the equation: {\displaystyle RM=GZ\cdot \Delta } RM=GZ\cdot \Delta Where RM is the righting moment, GZ is the righting arm and Δ is the displacement. Because the vessel displacement is constant, common practice is to simply graph the righting arm vs the angle of heel. The righting arm (known also as GZ — see diagram): the horizontal distance between the lines of buoyancy and gravity. https://en.wikipedia.org/wiki/Metacentric_height -------------------------------------------------- Note added at 1 hr (2017-10-20 12:04:14 GMT) -------------------------------------------------- Oops, question has already been closed ...
