A bone screw deforms on the same order as the bone, thus providing substantially uniform loading along an entire length of the thread of the bone screw. The bone screw of the present invention evenly distributes stress by matching the effective cross-sectional area of the bone screw times its modulus of elasticity with the effective cross-sectional area of the parent material (i.e. bone) times its modulus of elasticity so that they are preferably substantially equal to each other.

Embodiments of the present invention generally relate to an apparatus for supporting a tubular that more evenly distributes stress along the contact length of a tubular than prior art designs. In one embodiment, an apparatus for supporting a tubular is provided. The apparatus includes a bowl having a longitudinal opening extending therethrough and an inner surface for receiving a gripping member. The gripping member is movable along the surface of the bowl for engaging the tubular. The apparatus is configured so that an upper portion of the gripping member will engage the tubular before the rest of the gripping member engages the tubular.

An internal combustion engine connecting rod, having an embodiment defining a hollow beam member and a process of manufacture are disclosed.
