Nebraska Tractor Tests

EXPLANATION OF TEST REPORT: John Deere MC TEST A: The manufacturer's representative operates the tractor for a minimum of 12 hours using light to heavy drawbar loads in each gear. This serves as a period for limber up, general observation and adjustments. Adjustments that are permissible include valve tappet clearance, breaker ,point gap, spark plug gaps, clutch and others of a similar nature. No new parts or accessories can be installed without having mention made of it in the report. No data' are recorded during this preliminary run except the time that the engine is operated.

The Design, Construction, And Operation Of A Guarded Hot Box, Don Williams Jr.

Mechanical Engineering ETDs

The guarded hot box is a device for measuring the coefficient of heat transfer through typical wall sections, and, with some modifications, through insulations. In order to determine this coefficient, it is necessary to know the temperature difference across the wall and the quantity of heat flowing through a given area of the test sample when thermal equilibrium has been reached.

A Study Of A Small Hydrofoil Boat With Airplane Type Controls, Allyn B. Hazard

Mechanical Engineering ETDs

The primary purpose of this study was to determine if the application of airplane type controls to the hydrofoil boat would produce a stable craft that would be safe to operate. The secondary purpose of this study was to determine if a human operator could respond to changes in the boat's attitude brought on by wave action or other factors in time to keep the craft running in a desirable operating condition. Finally, the commercial possibilities were to be determined by the performance of the prototype.

Analytical Investigation Of Bending Effects On The Stability Of A Tube Subjected To External Pressure, Charles Young

Masters Theses

"The behavior of thin and moderately thick-walled tubes under various types of loadings has been a major problem of several leading industries for many years. Predominant among these, and the one for which this thesis was primarily undertaken, is the oil industry. The problem attacked in this thesis, however, is not limited to that industry alone, having ample application in industries that are sub-marine in nature, or any industry in which the application of external pressures on equipment is likely to be responsible for buckling failures...In this thesis, the problem of finding the effect of bending on the collapsing pressure …

Hydraulic Scale For Measurement Of Dynamometer And Other Forces, John Richard Barton

Masters Theses

"The object of this investigation is to design, build, test, and develop, a hydraulic type scale primarily to be used for measuring dynamometer forces. The scale however is not limited to use on dynamometers, but may be used for other types of force measurements such as the continuous weighing of material on a conveyor belt in conjunction with a recording pressure gage. The scale has numerous applications in determining forces where conventional scales are now used. This particular subject was chosen because of the need for a convenient, inexpensive, and accurate scale for use in measuring the force exerted by …

Periodic Heat Flow In A Semi-Infinite Solid, Warren George Heidbrier

Masters Theses

"The object of this investigation is to determine by analytical means the temperature within a homogeneous semi-infinite solid, as a function of time, while the solid is receiving heat periodically by radiation on its one flat surface. Periodic heat flow means that heat flow is a continuous function of time and repeats itself at regular intervals. A semi-infinite solid has only one bounding plane and extends to infinity in all other directions...Much of this work deals with the soil temperatures of the earth both at the surface and at various depths. The surface of the earth is subjected to daily …

The Temperature Within A Homogeneous Plate Of Finite Thickness, Charles R. Remington

Masters Theses

"The object of this thesis is to determine by an analytical method the temperature within a homogeneous plate of finite thickness subjected to a constant temperature on one side and a periodic fluctuating temperature, expressible in a Fourier series, on the opposite side. This problem in periodic temperature changes has not, to the author's knowledge, been solved previously. The flow of heat in the problem is considered in only one direction, the x-direction. Flow in the other two directions is considered negligible, or zero. Periodic temperature changes in the earth are of importance. The temperature changes have been used by …

The Application Of The Relaxation Method To The Solution Of Steady-State Heat Transfer Through A Concentric Square Insulator, William Edward Simpkin

Masters Theses

"It is the object of this thesis to express the relationship between the heat transfer through a square insulator of variable inside-outside dimension ratios, in terms of a concentric round insulator of the same inside-outside diameter ration, by means of a continuous curve. Mathematically speaking, this thesis will have a plot of a variable coefficient, c_s, to be used...in terms of the ratio of the width of the outside square to the width of the inside square"--Statement of Problem, page 8.
