Answer» Right option is (a) True The best explanation: Sharp CORNERS in the CASTING DESIGN causes hot spots which produce many casting defects, such as hot tears, metal penetration, shrinkage, cracking and gas-related defects. And the sharp edges on the metal are also prone to breaking off and MAY cause SAND inclu¬sions in the casting.
