Having placed in the scale the same weight as was used in the first experiment, the temperature was raised, by means of the moveable furnace, to "i such a point that the bar was rapidly giving way. The standard piece was withdrawn and tried twice, .giving, successively, the temperatures marked. Part now in the machine from 3$ to 10J Same part under trial as in the preceding exp't. f The scale was now loaded with four-fifths of the breaking weight in the first experiment. The dif ference of areas caused an excess of 452 lbs. above 1 four-fifths of the strength exhibited in that experiLment. Bar not actually parted. Part in tin from 22 to 25. The weight employed $ of that used in the first experiment. Section larger, hence the strength is 978 lbs. less than $ of 56759. The length from 23 to 24 was now 1.46 in. Not actually parted. C The same section as that tried in the preceding experiment. The mean area of 15 sections of fracture is.000062 square inch greater than the mean area of the 27 measured sections. TABLE LXIII. Experiments on bars No. 213a and 214a, taken respectively from bars 213 and 214. Seduced by hammering and filing to a nearly uniform J TABLE LXIII. J size, and then gauged at every inch. These bars ivere both hammered I until cold, technically "hammer-hardened." The mean area of these 4 sections of fracture is.000506 square inch Itss than the mean area of the 9 measured sections. The mean area of these 4 sections of fracture is.000498 square inch greater than the mean area of the 10 measured sections. TABLE LXIV. Experiments on a specimen of iron wire.
