Abstract
A load bearing apparatus includes a first container having enclosed ends and at least one expansion segment. The expansion segment includes a first cylinder and a second cylinder of diameter smaller than the first cylinder disposed along a longitudinal axis of the first cylinder. An elastomer seal is connected between the first and second cylinders to form a fluid tight seal between the cylinders. The elastomer seal further permits translation of the first cylinder with respect to the second cylinder in a direction along the longitudinal axis of the first cylinder.
