1.	Jolt and squeezing can be used for achieving uniform strength if the height of the mold is up to 200 mm.(a) True(b) FalseI have been asked this question by my school teacher while I was bunking the class.I'd like to ask this question from Methods of Ramming Mold Boxes in section Mold and Mold Making of Casting-Forming-Welding I
Answer» Correct answer is (a) True To EXPLAIN: JOLT and squeezing is a combination of jolting and squeezing. First of all jolting is done followed by squeezing. If the height of mold is LESS than 200 mm, throughout the depth of mold uniform strength is achieved. If the height of mold is more than 200 mm, the FORCE will not transmit to the MIDDLE portion of mold hence, less strength at center.
