註釋Ten 24S-T cylinders of 20-inch diameter, 45- or 58-inch length, and 0.012-inch wall thickness, reinforced with 24S-T aluminum alloy stringers and rings were tested in pure bending. In the middel of the compression side of the cylinders there was a cutout extending over 19 inches in the longitudinal direction, and over an angle of 45, 90, or 135 degrees in the circumferential direction. The strain in the stringers and in the sheet covering ws measured with metalectric strain gages.
