1.	In finishing of a pattern, fillets are provided to eliminate the stresses completely from the metal casting.(a) True(b) FalseThis question was posed to me during an online interview.Origin of the question is Finishing Patterns & Storing of Patterns in portion Pattern and Pattern Making of Casting-Forming-Welding I
Answer» The correct option is (b) False To elaborate: STRESSES cannot be eliminated COMPLETELY, only it can be reduced or distributed to the more part of the MATERIAL. Fillet Radius makes the casting stronger because it redirects stresses from being concentrated at a sharp internal corner and distributes them over the BROADER volume of the fillet material.
