Shear Stress Distribution In Haunched Beam Models, Manyu K. Mehta

Masters Theses

"The purpose of this thesis has been to give the distribution of shear stress inside a haunch. A haunch is generally provided to relieve high stress concentrations at the face of the column. However the nature of shear stress distribution inside the haunch is not known.

This stress distribution was determined from a photo- elastic study on a CR-39 model. It is noted that the haunch reduces the stress concentration at the face of the column but at the same time somewhere near the point where the haunch meets the beam there is a high stress concentration.

Shear stress changes …

Velocity Distribution Induced By Free Jet Impact On A Stilling Basin, Sedat Özkol

Masters Theses

"At present, the use of the free jet impacting on a stilling basin as an energy dissipator is not very common, as there is very little information available concerning this particular field. However, if conditions are favorable, this type of energy dissipator will be quite economical to construct.

In this paper it was found that the hydraulic behavior of the free jet impacting on a stilling basin can be determined to a degree which may be considered accurate for practical purposes. It was also shown that given the free jet velocity, the magnitudes of the velocities at the critical points …

Linear Feedback Control System Compensator Design Under Specified Constraints, Keikhosrow Irani

Masters Theses

"The purpose of this thesis is to find the necessary and sufficient conditions for the design of compensators, following the concepts developed by Ross, Warren, Hsu and Sanden.

The main object that motivates this investigation is to design the lead or lag compensator networks for a given linear feedback system when there are these constraints.

1. Gain of the system is constant.
2. The steady-state error is invariant.
3. The dominant poles of the closed-loop transfer function are specified.

Consideration of the problem is in two parts:

• a. Derivation of necessary and sufficient conditions of compensator design that fulfill the three constraints.
• b. …

Mechanics Of The Voussoir Arch As Applied To Block Caving, Christopher Haycocks

Masters Theses

"The theories of ground failure in massive rock with special reference to the problem of the mechanics of block caving were studied and evaluated.

The mechanics of arch or dome formation underground were studied quantitatively using the Voussoir arch theory. The effect of shear stress on the arch stability was considered and found to affect the system only when the arch height increased beyond certain limits.

A theory of the mechanism of ground failure in an undercut block using the dome theory was advanced. Photo- elastic model studies were used to support the conclusions reached"--Abstract, page i.

A Model Study Of The Behavior Of Elastic Liners In Shallow Underground Openings, Martin Samuel Oudenhoven

Masters Theses

"Models of epoxy resin were used in a stress freezing technique to determine areas of possible failure in lined circular openings. These models were loaded in a centrifuge for a fixed period of time, after which they were analyzed photoelastically. The material characteristic changes, with time, were recorded on graphs and used in the analysis.

Two types of tests were conducted; one, where the lining thickness was changed and, the other, where materials of the liner and plate material were changed.

The resulting analyses furnished proof that the greater the rigidity of the lining, the higher the stress developed in …

A Comparison Of A-C And D-C Lead Compensation From D-C Prototype Networks, Piyush Parikh

Masters Theses

"The object of this thesis is to study the difference in transient and frequency response characteristics between a prototype d-c phase lead compensating network and an equivalent a-c phase lead compensating network.

A second order servo is selected to be compensated and five d-c prototype and equivalent a-c phase lead compensating networks are designed. The frequency characteristics of the a-c networks are obtained experimentally and these of the d-c networks are obtained analytically. The characteristics of both networks are compared and their differences are studied. The transient characteristics of the d-c and a-c compensated closed-loop systems to a step input …

A Model Study Of The Induction Log Applied To The Detection Of Asymmetrically Located Orebodies, Robert Walter Piekarz

Masters Theses

"This research project was undertaken to determine the possibility of using an induction log of the type applied in petroleum exploration, for the detection of conductive ore- bodies asymmetrically located with respect to a borehole. Since a mathematical analysis would be extremely complex, a model study was conducted, using graphite bodies of various shapes to simulate different modes of mineral occurence.

The investigation showed that these bodies were readily detectable, and were capable of yielding anomalous curves characteristic of their geometry. The values of apparent conductivity decreased rapidly with lateral displacement, from the logging tool, as expected, due to the …

A Correlation Of Heat Transfer Coefficients Using An Induction Heater, Charles Maurice Martin

Masters Theses

"This thesis represents a study of the following problems. (1) Determination of techniques and equipment which would give satisfactory correlation of experimental heat transfer coefficients with those obtained from acceptable heat transfer equations when using an induction heater as the heat source. (2) Determination of depth of energy deposition in a thick-walled tube due to induction heating.

Techniques were developed that gave a correlation between experimental and calculated coefficients that were within -5% for minimum flow and +8% for maximum flow.

Because of difficulties in positioning thermocouples, the depth of energy deposition could not be accurately determined. However, two surface …

A Comparison Of The Load Carrying Characteristics Of Hydrostatic Thrust Bearing Using Monatomic, Diatomic, And Triatomic Gases, Joseph C. Pigott

Masters Theses

"The purpose of this investigation is to compare the load carrying characteristics of gases with different ratios of specific heat. The design, construction, and operation of an apparatus for testing and comparing the load carrying characteristics of gases are described. Several monatomic, diatomic, and triatomic gases were tested and the results evaluated and compared. The data are tabulated and displayed in a series of curves.

It was found that the monatomic gases exhibit a greater clearance for a given load and a greater total load carrying capacity than the diatomic gases which in turn have a greater clearance and total …

A Comparison Of Backwater Profile Computation, Alwin Chang Hsin Young

Masters Theses

"Bakhmeteff's, Von Seggern's, and the Standard Step methods were chosen for a comparative study of backwater profile determinations made with the assistance of a digital computer. This study concentrated on the M-l type of curves for different kind of prismatic channels; i.e. rectangular, trapezoidal, and parabolic channels. From the results obtained by each method for different channels, the consistency between the several methods and their applicability to all shapes of channel had been studied. Also the effect of the number of reaches used in flow profile determinations, the effect of the use of an average value of (1-ß), hydraulic exponents …
