Spherical Pair
A spherical pair allows three degrees of freedom since the complete description of relative movement between the connected elements needs three independent cooordinates.Two of the coordinates 'alpha' and 'beta' are required to specify the position of the axis OA and the third coordinate 'theta' describes the rotatio about the axis OA.
