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 …

Runoff And Soil Moisture, John William Clark Jr.

Masters Theses

"Hydrology is the science treating of water from the time it hits the earth until it leaves the earth. This never ending movement of water is called the "hydrologic cycle" and is best summarized graphically. The hydrologist is primarily concerned with rainfall, runoff and evaporation. One of the basic aims of the science is to compute the surface runoff from any rain on a given area. Surface runoff is here considered as that water which reaches the channels without penetrating the ground, plus subsurface storm flow. Subsurface storm flow is slower than surface runoff but faster than ground water flow. …

A Petrographic And Chemical Study Of The Bevier Coal Seam, Philip John Clarke

Masters Theses

"Samples of coal were taken at three inch intervals vertically down the Bevier seam at three localities in Macon and Randolph Counties. Channel samples were collected at the three localities. All samples were analyzed for ash content, total sulphur content, crucible swelling number, and volatile content. The channel samples were analyzed for "pyritic" sulphur, “sulphate" sulphur, and "organic" sulphur. Thin sections of the samples were used in an estimation of anthraxylon and attritus contents.

In all the samples studied, volatile content of the coal seemed to be related to the ash content and the sulphur content. Crucible swelling number also …

A.C. Circuit Interruption, Palmer L. Anthony Jr.

Masters Theses

"In the last few years the transmission voltages have increased tremendously. Along with the voltage increase came increased load carrying ability for the circuits. The first few links of a new 330 KV transmission system are now under construction in this country. Sweden is already operating a 380 KV line. It is expected to carry a load as high as 850,000 KW on a single circuit.

Interconnection between systems in adjoining areas is a practice to get further operating benefits. The benefits are - reduction of necessary reserve capacity, increased load diversity, and decreasing losses.

Both of these developments bring …

Plastic Deformation Of Rocks, Muhammed Abdul Waheb

Masters Theses

"The purpose of this investigation is to search for a method by which the strength properties of a rock may be described.

For this purpose, an attempt has been made to find out some relationship by which the rooks may be classified or described. For the solution of problems of mine stability, the mechanical properties of a rock should be known, i.e., hardness, toughness and strength. It is difficult to make a study of some method of classification or description of a rock without knowledge of these properties.

With a view to achieve the solution of a general classification for …

A Study Of Immiscibility In The Carbonates From The Metamorphic Rocks Of Southeastern Vermont, Ralph D. Cotter

Masters Theses

"This problem is an attempt to correlate grade of metamorphism (normally assumed to be temperature dependent) with the shape and dimensions of a solid miscibility gap. Such a correlation might permit mapping of a continuously variable function of metamorphism. The system, calcite and dolomite-ankerite, was chosen for study because of its relative simplicity. Samples of quartz-carbonate granulite were collected from the Waits River formation in southeastern Vermont through a range of metamorphic grades. Refractive index, "molecular" volume, manganese content, and density were determined for the carbonates of four of these samples. These values are plotted on a compositional diagram to …

The Lattice Constant And Coefficient Of Expansion Of Chromium, Chao-Ching Weng

Masters Theses

"The most important use of chromium, other than as an alloying element in the manufacture of stainless steel, is for electroplating; to form a coating on other metals for corrosion prevention in order to procure longer life, and to achieve a decorative effect.

The physical properties of chromium are important in the effectiveness of its uses, and its lattice constant, as well as coefficient of thermal expansion, seem worthy of exact determination.

A number of research workers, over a span of thirty years, have spent considerable effort in determining the aforementioned constants. However, their results do not check, and the …

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 …

A Linear Polymer X-Ray Scattering Model, Bernard Cohen

Masters Theses

"In the development of X-ray scattering intensity curves physical models are necessary for the theoretical mathematical development involved. The purpose of this paper is the development of a physical model suitable for X-ray diffraction analysis or a linear polymer.

X-ray intensity patterns may be used to give a greater insight as to the atomic structure, configuration or atoms, molecular weight, and therefore a greater knowledge of the structure of matter, both microscopic and macroscopic. The converse may sometimes be used. An atom or molecular model is constructed, from this model X-ray scattering curves may be derived. These curves may be …

The Fluorescence Of Uranium In Solid Solution, Robert Emmett Kelly

Masters Theses

"The fluorescence of uranium finds its greatest application in the so-called "bead test" which is a method of qualitative analysis. In the form of a bead, the uranium is in solid solution, and if the proper chemical solvent is used, the bead will fluoresce under ultraviolet radiation.

In the systematic separation of the metallic elements, uranium is associated with the aluminum group in that it is not precipitated by hydrogen sulfide in 0.3 N H ion but is precipitated by ammonium hydroxide and ammonium sulfide. In the analytical scheme, uranium acts like beryllium. This process of detection is sometimes tedious …

The Effect Of Impeller Speed And Air-Volume On The Flotation Rate With Respect To Particle Size, William Edward Horst

Masters Theses

"Today the ore being mined is low grade and the mineralization has become very complex. In order to concentrate a complex ore, the requirement of grinding the ore very fine is imposed. The process of flotation was developed to concentrate the finely ground ore particles; however, the finer size fractions of the ore still present a concentrating problem.

The fact has been established that the flotation rate which is the recovery that can be attained during a given time interval varies with particle size. The flotation rate increases with an increase in particle size until the maximum flotation rate is …

X-Ray Studies Of Zirconium Cyanonitride, John T. Ballass

Masters Theses

"The purpose of this research was to study, by means of x-ray and metallographic analysis, a material reported to be zirconium cyanonitride.

The x-ray analysis had a three fold purpose, the determination of the symmetry of the constituents, the number of phases present, and the crystal structure type. Metallography was used to confirm some of the results obtained by x-ray analysis establishing certain definite phase relationships present in the microstructure.

The sample investigated contained three principal elements namely zirconium, nitrogen, and carbon. On the basis of constitution this work is a contribution toward the development of the three component equilibrum …

Clipper Amplitude Modulator, Durmuş Öcal

Masters Theses

"An amplitude modulated wave is defined as a wave form in which the amplitude of a sinusoidal signal (carrier) is varied in accordance with a modulating signal whose frequency is much lower than the frequency of the carrier signal. Numerous devices have been found for generating an amplitude modulated wave. In some modulators the amplitude of the carrier is actually varied in accordance with the modulating signal. In other types of modulators the carrier and the modulating signal are simultaneously applied to a nonlinear element or circuit. The output of this non-linear element is a distorted wave containing many frequencies. …
