A method for providing torque to assist in moving a component of a mobile platform. Biasing forces may be applied to opposing portions of a torque transferring member that enable the torque transferring member to be maintained in a position of equilibrium. A torque may be applied to one of the component and the torque transferring member such that the biasing forces cooperatively exert a torque on the torque transferring member to assist in moving the torque transferring member out from the position of equilibrium. Motion of the torque transferring member out from the position of equilibrium may be used to assist in moving the component.

1. A method for providing torque to assist in moving a component of a mobile platform, the method comprising: applying biasing forces to opposing portions of a torque transferring member, through a pair of assist assemblies each having a threaded mechanism to enable a user adjustable preload force to be applied to said opposing portions of said torque transferring member, to exert axially aligned, opposing preload forces on said torque transferring member that enable said torque transferring member to be maintained in a position of equilibrium;applying a torque to one of said component and said torque transferring member such that axially opposing preload forces are moved out of axial opposing alignment with one another, to thus cause said biasing forces to cooperatively exert a torque on said torque transferring member to assist in moving said torque transferring member out from said position of equilibrium; andusing said motion of said torque transferring member out from said position of equilibrium to exert a torque on said component to assist in moving said component. 2. The method of claim 1, wherein said applying biasing forces to opposing portions of said torque transferring member comprises using a pair of coil springs arranged to exert counteracting forces on said torque transferring member when said torque transferring member is in said position of equilibrium. 3. The method of claim 2, wherein said applying biasing forces to said opposing portions of said torque transferring member comprises aligning an axial center of each of said coil springs and operatively coupling each of said coil springs via a pair of pivotal links with said torque transferring member. 4. The method of claim 1, wherein said applying biasing forces to opposing portions of a torque transferring member comprises using a pair of Belleville washers arranged to exert counteracting forces on said torque transferring member when said torque transferring member is in said position of equilibrium. 5. The method of claim 1, wherein said applying biasing forces comprises using one of coil springs and Belleville washers that are installed relative to said torque transferring member to be under compression when said torque transferring member is in said position of equilibrium. 6. The method of claim 5, wherein said applying a torque to one of said torque transferring member and said component comprises using an independent actuator. 7. The method of claim 1, wherein said using motion of said torque transferring member to assist in moving said component comprises using motion of said torque transferring member to assist in moving a flight control component of an airborne mobile platform. 8. A method for providing a torque to a flight control component of an airborne mobile platform to assist in moving said flight control component, the method comprising: coupling a torque transferring member to said flight control component to assist in moving the flight control component;disposing a biasing member under one of controlled amount of compression and a controlled amount of tension, relative to said torque transferring member, to exert a user adjustable preload force, via a threaded adjustment mechanism and a pivotal link, on said torque transferring member that acts to apply a torque on said torque transferring member when said torque transferring member is moved from a first position of equilibrium, wherein in said first position said preload force is directed along a linear path through the pivotal link, along an axial center of the biasing member, and through an axial center of said torque transferring member and thus causes no rotation causing torque to be applied to said torque transferring member, to a second position wherein, in said second position, said pivotal link applies said preload force along an axis that does not extend through an axial center of said torque transferring member, to thus cause said torque transferring member to exert a torque on said flight control component; andusing an actuator to initiate movement of one of said torque transferring member and said component to urge said torque transferring component into said second position, wherein said preload force from said biasing member assists in urging said torque transferring member to move rotationally to said second position. 9. The method of claim 8, wherein disposing a biasing member comprises disposing at least one Belleville washer under compression. 10. The method of claim 9, wherein disposing a Belleville washer comprises disposing a plurality of Belleville washers stacked adjacent one another. 11. The method of claim 8, further comprising disposing an additional biasing member to exert one of compression and tension relative to said torque transferring member, and such that said biasing member and said additional biasing member work cooperatively to maintain said torque transferring member in said first position of equilibrium, and where said biasing member and said additional biasing member cooperate to urge said torque transferring member rotationally when said torque transferring member is moved out of said first position of equilibrium toward said second position. 12. The method of claim 11, wherein said biasing member and said additional biasing member are arranged so that their axial centers are aligned. 13. The method of claim 12, further comprising coupling said additional biasing member via an additional pivotal link to said torque transferring member. 14. A method for moving a flight control structure on an airborne mobile platform between first and second positions in a manner that overcomes an inherent structural stiffness of the structure, comprising: coupling at least one end of a force transferring member fixedly to said structure;loading a biasing element, while said structure is being held in said first position, with a controlled preload force, via a user adjustable threaded mechanism, such that the biasing element exerts a preload force aligned with an axial center of said force transferring member, and which is sufficient to substantially hold said structure in said first position;loading an additional biasing element such that said biasing element and said additional biasing element produce counteracting and offsetting controlled preload forces when said structure is in said first position;further comprising arranging said biasing element and said additional biasing element such that an axial center of each is aligned;using said preload force applied by said biasing element to move said torque transferring member when said preload force is directed away from said axial center of said force transferring member, so as to assist in moving said structure from said first position to said second position when movement of said structure is initiated by an external component, to thus substantially transfer said stored energy of said biasing element to said structure through said torque transferring member; andusing said biasing element to again store said energy when said structure is moved from said second position back to said first position. 15. The method of claim 14, wherein said first position represents a position of equilibrium where a substantially reduced force is required to maintain said structure against movement. 16. The method of claim 14, wherein said biasing element provides a non-linear spring force that enables said structure to be moved from said second position back into said first position with less force than that needed to move said structure from said first position into said second position.
