| Title | Paper, 'The effects of mechanical stress on the electrical resistance of metals' by James H Gray and James B Henderson |
| Creator | Gray; James H (fl 1893) |
| Henderson; James B (fl 1893) |
| Date | 1893 |
| Description | The authors write: 'This investigation was begun under the instructions of Lord Kelvin about a year ago, and has been continued since the beginning of last year in conjunction with another on thermal conductivity, for which a grant of £50 was made from the Government Research Fund. The chief object of the investigation was to obtain quantitative results of the variations of specific resistances of metals due to stretching, twisting, drawing through holes in a steel plate, hammering, heating, and combinations of these, while in some of these cases the alteration of density was also measured.'
Annotations in pencil and ink. Includes four diagrams of experimental apparatus and results.
