Buoyancy situation of fluid statics such that Archimedes principle is applicable, and is thus the sum of the buoyancy force and the object's weight If the buoyancy of an (unrestrained and unpowered) object exceeds its weight, it tends to rise. An object whose weight exceeds its buoyancy tends to sink. Calculation of the upwards force on a submerged object during its accelerating period cannot be done by the Archimedes principle alone; it is necessary to consider dynamics of an object involving buoyancy. Once it fully sinks to the floor of the fluid or rises to the surface and settles, Archimedes principle
Legend of the Leather Bridge of Mümpelgard (Montbéliard), Count of Oltigen they came to an evil end in May 1410, according to Conrad Justinger. Legend of the Leather Bridge There is a legend of the Leather Bridge () in several regions of Germany and Switzerland. The word "lederne" could also have meant "ladder" or "lantern". According to legend, there was once a leather bridge crossing the Elmstein valley between the Palatine castle of Erfenstein, high above the left bank of the Speyerbach river, and a second castle, Spangenberg, on the opposite side of the valley.
