Two designs A and B, shown in the figure, are proposed for a thin-walled closed
section that is expected to carry only torque. Both A and B have a semi-circular
nose, and are made of the same material with a wall thickness of 1 mm. With
strength as the only criterion for failure, the ratio of maximum torque that B can
support to the maximum torque that A can support is__ (rounded off to two
decimal places).
