When a skin panel is idealised into booms, the area added to each adjacent boom depends on

  • A.The stress ratio across the panel
  • B.The length of the panel only
  • C.The shear flow in the panel
  • D.The material's Young's modulus

Answer: A

The standard boom formula shares the panel's area between its two ends in proportion to a term containing the stress ratio, so that the idealised section carries the same direct load as the real one. For a panel in uniform stress the split is simply half to each end.
