| 520 | 3 | |a The purpose of this study was to develop an inexpensive interface between the Vega universal testing machine and a Commodore-64 microcomputer. Also, to develop a computer program that will store and retrieve pertinent information about the metallurgical properties of tensile specimens (i.e., modulus of elasticity, Brinell Hardness number, yield point, reduction of area, tempering temperature, etc.). Also, compare the interfacing with the conventional method. It is theorized that by interfacing the Vega universal testing machine with the Commodore-64 microcomputer, the metallurgical data calculated by the computer will be equal to the metallurgical data calculated by the conventional method. Out of eleven hypotheses, there were nine hypotheses with significant difference at the ninety-five percent confidence level. Two hypotheses had no differences. These were the percent elongation and unit deformation. The percent elongation is a multiple of the unit deformation by 100 times. The computer was faster overall than the conventional method. However, the regression predictive equation used in the computer program to calculate the metallurgical data produced on the average higher values than the conventional method. The predictive equation can be adjusted to calculate values that are equivalent to the correct values for any given specimen. | |
