Crimp Method Of Closure Of Small Pressure Vessels, Zafiri Bersu

Masters Theses

"The object of this thesis is to design a means of closing the ends of thin aluminum alloy tubing in the 1” O.D. to 2” O.D. by .035 to .065 inch thick sizes, so that the closure will withstand internal hydrostatic pressure sufficient to burst the tube along the longitudinal element.

The aim is to approach the ultimate mechanical efficiency possible, and at the same time to keep actual production in mind.…

Summarizing the aims of this investigation, it can be said that the objectives of this investigation are:

1. To design ends for closed vessels.
2. To form the designs.
3. To …

Photoelastic Investigation Of The Stresses In A Capless Connecting Rod, Gerald Delaine Smith

Masters Theses

"For a great many years the primary method used to solve engineering problems was by the use of mathematics. However, rigorous and simple mathematical solutions are only possible if the geometry of the member and its loadings are relatively simple. When irregular shapes with complex loadings are encountered, rigorous mathematical solutions for stresses induced are either impossible or very cumbersome. In such cases, the engineer must resort to other methods which are available today.

This paper attempts to show the application of the photoelastic method to such a problem. Moreover, it will show the comparative ease with which the designer …

Effect Of Viscosity On The Cetane Number Of A Diesel Fuel, Moris Bolay

Masters Theses

"The object of this paper is to determine or rather experimentally establish the effect of a change in viscosity of a given diesel oil in regard to the ignition quality (cetane rating) of the oil.

The author did not attempt to prove why or find out how much the cetane number was affected. But, merely, tried to experimentally verify the fact that the cetane number of the fuel used underwent a change when its viscosity was decreased by preheating it.

Since his professional interests lie in the field of automotive engineering, several thesis problems were suggested to him by Dr. …

The Holding Strength Of Crimps On Tubes, Aydin Cansever

Masters Theses

"The object of this thesis is to determine by analytical means and laboratory tests the holding force of various crimp methods of fastening sheet metals and special tubing. The study is conducted with heat treated Aluminum alloy 24S.T3.

The problem of joining relatively thin walled tubing of high strength material or the application of a plug to such a tube has been investigated by many manufacturers, but the literature in this field is limited and still there are many cases where a better method may prove very useful. At the suggestion of Dr. Aaron J. Miles, the author decided to …

Nebraska Tractor Tests

EXPLANATION OF TEST REPORT: John Deere 60 LPG 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.

This report and any related files are made available to the online through the Lester F. Larsen Tractor Test and Power Museum as resources allow. Established in 1998, this museum is located on the University of Nebraska-Lincoln East Campus. 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 …

Development Of A Test For Rapid Determination Of Octane Ratings Of Gasolines, Charles B. Gangwer

Mechanical Engineering ETDs

For many years, the Mechanical Engineering Department of the University of New Mexico has been interested in developing a more reliable and expedient method to determine octane readings of gasolines than the conventional CFR Motor Method of Test for Knock Characteristics of Motor Fuels. A summary of the development of the conventional CFR Test method and a brief discussion of the operational procedure of this method is necessary to better understand the need for a new fuel rating procedure. To further explain the disadvantages of the conventional test method, an introduction to the new test method to be developed will …

The Design, Construction, And Calibration Of A Stationary Wave Device For Determining Sound Absorption Coefficients Of Acoustic Materials, Douglas W. Ballard

Mechanical Engineering ETDs

The general scope of the thesis investigation is limited to the engineering design and construction of a stationary-wave device for the experimental determination of the sound absorption coefficients of various building materials, the calibration of the apparatus to give comparisons with results obtained in the more expensive reverberation method, and to attempt to correlate observed results with generally accepted acoustical standards.

Development Of Electro-Mechanical Equipment For The Measurement Of Knock Characteristics Of Gasolines, Rudolph W. Ebacher

Mechanical Engineering ETDs

It was considered by the writer that characteristics of oscilloscope wave forms representing the varying pressures taking place in the CFR engine cylinder might provide an index to octane ratings of gasoline. Obtaining pressure wave forms on the oscilloscope required some medium for providing an electrical signal in response to engine cylinder pressures. A quartz pressure element was considered as the item that could fulfill this requirement.

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 …
