Abstract: A method of configuring a mount or of controlling sway in an object to be mounted includes configuring isolators of the mount to put a center of elasticity of the flexible mount at a desired height relative to a base of the mount. This desired distance may be at a location of expected minimum clearance between the object to be mounted and the structure expected to surround the object to be mounted and is the center of rotation of the flexible mount. The location of the center of elasticity also may be farther from the base than a center of mass or gravity of the object to be mounted. An equation relating the location of the center of elasticity as a function of isolator material properties and of angle between the isolators and the base may be used to analytically predict the location of the center of elasticity and the center of rotation.

Abstract: A foot pad has an elastic conical body and at least one elastic rib. The elastic conical body defines a connecting surface and an outer conical surface. The connecting surface defines a hollow portion, and the elastic rib integrally connects to the elastic conical body at a surface of the hollow portion.
