Solid diameter disc D can rotate under gravity about a horizontal axis passing through one of the points on the diameter of the disk perpendicular to its plane. The disc deviate from the equilibrium position by 90 ° and released. Is it possible to find the position of the axis, in which the movement of the disc to the position of the equilibrium will be minimal? If so, get this position.
