The star cross-section has six or eight lobes (depending on the model) compared to three on a triangular tube or two on a lemon tube. More lobes means more contact surfaces distributing the torque load. Each lobe carries a smaller fraction of the total force, which keeps stress per contact point well below the material’s yield strength even at peak loads.
