Abstract
Hardness is a measurable property of solid substances that reflects their ability to resist
permanent deformation. The hardness of a material determines its application. Hardness can be
measured in different ways. In this lab experiment, the Rockwell hardness tester was used. The
objective was to measure the hardness of the provided specimens and to compare the measure of
their hardness. Five specimens; A, B, C, D, and E were prepared and tested for hardness on the
Rockwell hardness tester. The correct procedures were followed in conducting the experiments.
Three tests were done on each specimen and readings were obtained. An average was calculated
from the three readings to obtain the hardness measure for each specimen. Specimen B had the
highest reading indicating that it was the hardest while D and E had the lowest. The objecti...
