1.	Predominant resistance in mould of casting system generally produces castings of brittle nature.(a) True(b) FalseThis question was posed to me by my college director while I was bunking the class.This intriguing question originated from Solidification with Predominant Resistance in Mould in portion Cooling and Solidification of Casting-Forming-Welding I
Answer» Right option is (b) False To explain I would say: DUE to predominant resistance in the mould of casting system, the heat transfer does not occur easily. However, it can be done forcefully, but in normal WAY the casting produced is of ductile NATURE as the heat is kept within the casting for a longer time. But, inaccurate way of solidification MIGHT cause defects in the casting.
