It is and appropriately housed within the walls of the historic 1920 Nebraska Tractor Test Laboratory, where the first tractor test was started on March 31st, 1920. Because the pioneer tests became worldwide standards, this location was designated as a Historic Landmark of Agricultural Engineering by the American Society of Agricultural Engineers in 1980, shortly after testing was moved to a …

The Effect Of Various Binders And Moisture Content On The Apparent Thermal Conductivity Of Green Foundry Sand, Robert V. Wolf Jan 1952

The Effect Of Various Binders And Moisture Content On The Apparent Thermal Conductivity Of Green Foundry Sand, Robert V. Wolf

Masters Theses

"The broad field of heat transfer is well developed in its theory and mathematics, however, some few applications of varying heat transfer rates have been explored only recently.

Previous to the nineteen-thirties, foundrymen had apparently been interested in heat transfer measurements only from the standpoint of the melting of metals and the heat treatment of the finished castings, with the rate of solidification and the transfer of heat from the casting through the mold being ignored, or at least accepted as an uncontrollable factor. This does not apply, of course, to the use of metal chills to adjust solidification rates …

Photoelastic Investigation Of Notched Corners In Square Apertures In Flat Plates Subjected To Tension, Lloyd E. Byrd Jr. Jan 1952

Photoelastic Investigation Of Notched Corners In Square Apertures In Flat Plates Subjected To Tension, Lloyd E. Byrd Jr.

Masters Theses

"Photoelastic stress analysis is one of the most effective methods available to the engineer for solving problems of stress distribution. The effect of forces, such as pressure and tension may be studied using a scale model of a structural part. Special transparent models are subjected to forces proportional to those acting on the real object. The stress problem produced in the model indicates the stress distribution through a cross-section of the structural part.

Analysis of the photographic record of the stress analysis pattern provides data with a high degree of accuracy within a relatively short time. In simple cases, this …
