<p>A force generator (90) includes an elongate force generator body that has a longitudinal dimension, and has a fluid chamber defined therein. The force generator body (90) exhibits a dimensional extension responsive to an increase in fluid in the fluid chamber, and a dimensional retraction responsive to a decrease in fluid in the fluid chamber. A restraint apparatus channels the dimensional extension/retraction into the longitudinal dimension, and restrains dimensional extension in a dimension transverse thereto.</p> |
