Brachistochrone curve
A brachistochrone curve (from Ancient Greek βράχιστος
χρόνος
(brákhistos khrónos) 'shortest time'),[ or
curve of fastest descent, is the one lying on the plane between a point A and a lower point B, where B is
not directly below A, on which a bead slides
frictionlessly under the influence of a uniform gravitational field to a given end point in the shortest time. The problem was posed by
Johann Bernoulli in 1696.
Here, it is simulated in Abaqus/Explicit.
