How can bone beat steel when a hammer snaps it?
Gram for gram, the bone in your thigh holds up under squeezing better than a steel bar.
Steel wins on raw force, but it is roughly four times heavier than bone for the same volume. Compare strength to weight instead, and cortical bone (the dense outer shell of your bones) edges out mild steel in compression - the kind of squeezing load your legs carry when you stand. This only holds for compression and only by weight, not for absolute force.
Think of carrying two backpacks of equal weight: one packed with steel, one with bone. The bone pack can prop up more squeezing load before it crushes, because so little of its weight is dead mass.
Strength-to-weight is a different contest from raw strength, and biology optimizes for the first.
It is why your skeleton can be light enough to run yet stiff enough to carry you - evolution traded raw strength for an unbeatable strength-to-weight ratio.
Steel is stronger; bone is lighter. Divide strength by weight and the light one wins at squeezing.
