1.	Which if the following is suggested in the shore scleroscope test to obtain the exact value?(a) Instrument should be in sunlight(b) Instrument should be spray painted(c) Instrument should be fixed rigidly(d) Instrument should be in sleeping positionI have been asked this question during an online exam.This intriguing question originated from Aircraft Materials topic in section Testing Aircraft Materials of Aerospace Materials & Processes
Answer» Correct ANSWER is (C) Instrument should be fixed rigidly The BEST explanation: The instrument should be fixed rigidly in a particular position to avoid MOVEMENT during the experiment. If any movement happens, it might AFFECT the accuracy of the obtained hardness number.
