Which ONE OR MORE tube cross-sections can be produced by true centrifugal casting? Sections are perpendicular to the rotation axis; drawings are not to scale.
Centrifugal force produces a circular free inner surface concentric with the rotation axis. The outer contour follows the mold and may be polygonal. B and C have circular bores; A and D have polygonal bores. Hence **B,C**.
