1.	What is the principal use of the impact tests?(a) To determine ductility(b) To determine if the material has been subjected to heat treatment(c) To prevent material from corroding(d) To obtain absolute valuesI had been asked this question in class test.The origin of the question is Impact Test topic in division Testing Aircraft Materials of Aerospace Materials & Processes
Answer» The correct choice is (b) To DETERMINE if the material has been subjected to heat treatment Explanation: The PRINCIPAL or main reason that the impact TEST is conducted upon a material is to ASCERTAIN if the material has undergone the required accurate heat treatment. The experiment gives no absolute value.
