A magnetorheological fluid actuated damper. At least a first and a second cylinder with the first cylinder positioned axially within the second cylinder are provided. A gap is formed between the cylinders. The second cylinder is mounted to a stationary mount of the vehicle chassis and a control arm is mounted at an end of the first cylinder. The first cylinder is mounted on bearings to allow it to rotate relative to the chassis. The gap between the cylinders contains a magnetorheological fluid having an adjustable viscosity in reaction to the application of a magnetic field. A magnetic field is generated over the fluid in the gap.

An aircraft tire chock, comprising: a. an elongated body with a triangular-shaped cross-section, said elongated body including three, longitudinally aligned support members; b. a plurality of triangular-shaped, spaced-apart gussets and located inside said elongated body and used to support said support members on said elongated body, said support members on said elongated body are spaced apart over the three sides of said gussets and sufficient in width to create a slot between adjacent said support members through which bumpers extend and, wherein; c. three bumpers are attached to said elongated body, said bumpers extending outward from said elongated body and between said support members to create a contact surface with the ground or a tire surface. 2. The aircraft tire chock as recited in claim 1, further including a pull handle attached to said elongated body. 3. The aircraft tire chock as recited in claim 2, wherein at least one end gusset is disposed near the end of said elongated body, said end gusset including a center bore through which said pull handle extends to connect to said elongated body. 4. The aircraft tire chock as recited in claim 3, further including a longitudinally aligned pipe extending through said center bore formed on said end gusset. 5. The aircraft tire chock as recited in claim 4, further including means to secure one end of said pull handle inside said-elongated body to prevent said pull handle from being removed from said elongated body when pulled. 6. The aircraft tire chock as recited in claim 4, wherein said pipe partially ends through two end caps attached to said opposite ends of said elongated body. 7. The aircraft tire chock as recited in claim 6, further including a selectively attachable locking means to attached each said end cap to said elongated body. 8. The aircraft tire chock as recited in claim 7, wherein said locking means is a set of threads formed on said pipe and a nut selectively attachable to said threads to lock each said end. cap in position on said pipe. 9. The aircraft tire chock as recited in claim 2, wherein said pull handle is a wire rope including a central cable covered with a protective, outer layer. 10. The aircraft tire chock as recited in claim 1, further including means to connect said bumpers to said gussets. 11. The aircraft tire chock as recited in claim 1, further including two triangular-shaped end caps attached to the opposite ends of said elongated body. 12. The aircraft tire chock as recited in claims 11, wherein each said end cap partially extends into said elongated body and is radially locked in position thereto. 13. The aircraft tire chock as recited in claim 11, wherein each said end cap is a flat plate attached to the ends of said elongated body. 14. The aircraft tire chock as recited in claim 1, further including a traction plate attached to the outer surface of at least one of said support members. 15. The aircraft tire chock as recited in claim 1, wherein said support members are made of lightweight, non-sparking material. 16. An aircraft tire chock, comprising: a. an elongated body, triangular-shaped in cross-section with three longitudinally aligned support members on said elongated body, said support members spaced apart thereby creating a gap between adjacent said support members; b. a plurality of gussets spaced apart and located inside said elongated body and used to support said support members; c. three outward-extended elongated bumpers disposed longitudinally between said support members; d. a pair of end caps attached to said elongated body; and, e. a pull handle attached to said elongated body. 17. The aircraft tire chock as recited in claims 16, wherein each said end cap is triangular-shaped and covers the ends of said bumpers. 18. The aircraft tire chock as recited in claim 16, wherein each said end cap is a flat plate attached to the ends of said elongated body. 19. The aircraft tire chock as recited in claim 1
