In a micro-Vickers hardness test, the diagonals of the indentation are 54 and 55 um when a load of 200 g was applied to the specimen. Determine the micro-Vickers hardness (HV) of the tested specimen. (Input the answer with two decimal places: like 20.32, 36.26, etc.).
During the test of hardness due to Brinell, the diameter of the testing sphere was0.01m, the exerted load was 3.0 tons and the diameter of the indented area wasapproximately 0.003 m. Find the value of the hardness for this material. Also find theTensile strength if the proportionality constant was approximately 3.45.
