A mounting system includes a rotatable machine, a frame circumscribing the rotatable machine, and a plurality of mounting elements. Each mounting element of the plurality of mounting elements includes a pin member and a joint member. The joint member includes a rotatable joint capable of three degrees of freedom of rotation, and the joint member is slidably coupled to the pin member, such that each mounting element is capable of four degrees of freedom of motion. The plurality of mounting elements are further coupled between the frame and the rotatable machine and spaced circumferentially about the rotatable machine, such that the rotatable machine is able to expand and contract radially within the frame. The mounting system provides a uniform stiffness in any radial direction from the engine centerline within the lateral-vertical engine plane.
