Abstract
A controllable strut (10) includes a helical spring (22) which extends between first and second end portions (12 and 14) of the strut (10). A field responsive fluid (30) is disposed about the spring. A source of electromagnetic energy (40) provides a magnetic field through at least a portion of the fluid (30) and the spring (22). The fluid viscosity changes with changes in the intensity of the magnetic field.
