Recent developments in the design of rigid airships, as commercial air liners in England and Germany, and for military purposes in America, show a demand for greater lifting capacity, cruising range and speed. The increase in size is mainly responsible for radical changes in the structural arrangement of the transverse frames, introduced by the designers of the British airships, R.100 and R.101.

Note on page 499 § This statement is not strictly true. For instance, in the stiff-jointed polygonal ring, the bending moment is reduced owing to the redistribution of load from the shear wires, but the shear across the transverse girder may be increased locally.
