A round casting is 0.2 m (7.9 in.) in diameter and 0.75 m (29.5 in.) in length. Another casting of thesame metal is elliptical in cross section, with a major-to-minor axis ratio of 2, and has the same lengthand cross sectional area as the round casting. Both pieces are cast under the same conditions. What isthe difference in the solidification times of the two castings?
