ME 3701 Chapter : Experiment 2 Instruction
Document Summary
The main objective of this experiment is to introduce two important basic mechanical property tests; hardness (using rockwell testing) and impact (using charpy testing). Chauvenet"s criterion will be applied to identify outliers and probability paper will be used to ascertain whether or not the repeated measure hardness data is normally distributed. The mechanical properties of materials are ascertained by performing carefully designed laboratory experiments that replicate, as nearly as practical, the service conditions. Factors to be considered include the nature of the applied load(s), its" duration and the applicable environmental conditions. It is possible for the load to be tensile, compressive, or shear, and its magnitude may be constant with time, or it may fluctuate continuously. Application time may be for only a fraction of a second, or it may extend over a period of many years. Service temperature can also be an important factor.
