Rules For Official Tractor Tests, Nebraska Tractor Test Lab, Agicultural Experiment Station

Nebraska Tractor Tests

The Nebraska Tractor Law known as House Roll 85, 37th session, which became effective July 15, 1919, was enacted to encourage the manufacture and sale of imporved types of tractors and to contribute to a more successful use of the tractor for farming.

It was thought that the best method of accomplishing these objects would be to require a tractor of each model sold in the State to be tested at the State University and to have the results of these tests made public. These tests will give reliable information on the power capacity and fuel consumtion of each tractor …

Rules For Tractor Demonstrations, Nebraska Tractor Test Lab

Nebraska Tractor Tests

The object of these rules, instructions and data is to make all tractor demonstrations of this kind comparable and of the greatest educational value. Anyone who has conducted tractor demonstrations in the past has realized the necessity of some standard rules to follow and those who afterwards have referred to the results, deplore the lack of uniformity in the demonstrations and the data. For those who have not had this experience will find that it is a great help to have satisfactory rules to follow.

The value of these demonstrations depends largely upon the accuracy of the data reported on …

Electric Double-Refraction In Carbon Disulphide At Low Potentials, Gustaf W. Elmen

University Studies (University of Nebraska): Papers

When light polarized at an angle of forty-five degrees to the lines of force is passed through certain dielectrics, between two parallel electrodes, they become double-refracting. The difference of phase, delta, between the two components of light at right angles and parallel to the lines of force, as represented by Kerr and verified by later investigators, is

δ = ± BP²l/a²

where B is the electro-optic constant, depending on, the dielectric, I the length, and a the distance between the plate' electrodes in centimeters, and P the difference of potential between the electrodes in C.G.S. units.
