1.	It is not necessary to avoid any sharp internal corners from casting design, as it causes very negligible problems.(a) True(b) FalseThe question was asked during an online interview.This intriguing question comes from Pattern Fillets topic in chapter Pattern and Pattern Making of Casting-Forming-Welding I
Answer» CORRECT option is (b) False Best explanation: SHARP INTERNAL corners on a casting design must be avoided whenever pos¬sible. The small VOLUME of melt located in a casting’s internal corner quickly BECOMES superheated and transfer of heat becomes very difficult at this location, this further results in the formation of defects in the casting.
