1.	In the mould, the heat experienced by the core is much severe than that of experienced by the mould wall.(a) True(b) FalseThis question was posed to me in a national level competition.My doubt is from Forces Acting on Cores and Mold topic in portion Mold and Mold Making of Casting-Forming-Welding I
Answer» Right choice is (a) True Explanation: In the mould, the core is surrounded by the MOLTEN METAL, so it experiences more thermal LOAD as compared to the mould wall. The mould wall experiences the HEAT which is exposed to the molten metal from one side only, but in the case of the core it is surrounded from all the sides. So, the heat experienced by the core is MUCH severe.
