Aircraft Quality Casting Standards, Robert Katz, Robert Bolin , Depositor

Robert Katz Publications

These standards are to be used in connection with the Handbook for Instructions for Aircraft Designers, 8^th Edition …

In the radiography of aircraft castings, markings appearing on the film may be attributed to either the condition of the castings examined, or to some details of the radiographic process entirely unrelated to the quality of the castings, These latter patterns must be recognized and related to the radiographic process so that sound castings will not be unnecessarily rejected. Radiographs must be carefully compared with the surface irregularities of the casting they represent before an attempt is made to …

School Of Civil Engineering Tests Of Light Beams Of Cold Formed Steel For The American Iron & Steel Inst., Cornell University School Of Civil Engineering

CCFSS Library (1939 - present)

I. SCOPE OF THE REPORT Six beams of the new series with unstiffened top flanges have been tested; viz., two specimens each of beams 12-3, 18-3 3/4, and 20-3 3/4. (The first number in this designation gives the gage thickness, the second the half-width of the top flange). This report contains only the data of the tests. The evaluation of the test results will be carried out after a larger number of beams have been tested.

An Analysis Of Pressure Gasoline And Pressure Kerosene Stoves, Arnold E. Baragar

Nebraska Agricultural Experiment Station: Historical Research Bulletins

During the past few years inquiries have been received regarding the cost of operation, efficiency, and performance of pressure gasoline and pressure kerosene stoves. Because of the method of operation and the use of gasoline as fuel, safety from fire and carbon monoxide has been frequently questioned. Not only is it necessary to have technical information about this type of appliance in order to compare it with other types but it is further important to know whether one type of burner is superior to another; whether one type of oven construction will give better results than another and in general …

Cornell University School Of Civil Engineering Tests On Light Beams Of Cold-Formed Steel, Cornell University School Of Civil Engineering

CCFSS Library (1939 - present)

SCOPE OF THIS REPORT all the beams heretofore tested in this program were furnished with web stiffeners in order to aviod crushing of the web at the load points and at the supports. In practical application the use of such stiffeners at points of concentrated loads would not only be uneconomical but also would impair the versatility of the elements, since stiffeners would have to be spaced on each individual beam according to the particular location and loading. For this reason it seem essential to investigate the resistance of unreinforced webs to concentrated loading. The tests reported herein are to …

Tests On Cold Formed Steel Studs For The American Iron And Steel Institute, American Iron And Steel Institute

CCFSS Library (1939 - present)

I. SCOPE OF THIS REPORT In the 12th Report, Section III, a method was proposed for the determination of the required strength of collateral attachments. In addition, a test procedure was suggested to test the validity of the theoretical considerations on which this determination was based. In the present report two more formulae are developed which will serve for the experimental verification of this approach. Preparations for these tests are now under way.

Tests On Light Beams Of Cold Formed Steel, American Iron And Steel Institute

CCFSS Library (1939 - present)

1. SCOPE OF THIS REPORT Failure tests have been carried out on beams 0-3, P-3/Q-3, I-1, I-2, I-3, H-1, H-2, H-3, and K-1. As mentioned in the Sixteenth Progress Report (p. 15) it was, anticipated that beams H,I,K, as originally designed, would fail in pure yielding. Since such a failure is not revealing for this investigation, an attempt was made to narrow both flanges of these beams. This work was done in the shops of the School of Civil Engineering and of the School of Mechanical Engineering. It turned out, however, that in cutting off parts of the flanges, the …

Test 369: Mccormick-Deering Model W-9 (Gasoline), Nebraska Tractor Test Lab

Nebraska Tractor Tests

All tractors tested at the Nebraska Tractor Test Laboratory were certified by their manufacturers as being stock model machines, conforming to specifications filed with the application for test. No special or high-test fuels were used except as recommended by the manufacturer as necessary.

All results within the official tractor test report were actually attained in tests and are without correction or allowances for friction, temperature, altitude, etc. The results were initially accomplished with the tractor in charge of skilled operators employed by the University.

Unless otherwise noted, each tractor was apparently in good condition at the end of the testing …

Cornell University School Of Civil Engineering Tests On Light Beams Of Cold-Formed Steel, Cornell University School Of Civil Engineering

CCFSS Library (1939 - present)

I. SCOPE OF THIS REPORT In the preceding 14th Progress Report a method was proposed to determine the forces acting in the welds in the web of I-beams composed of two channels. This method essentially has been based on the magnitude "e", the distance of the flexural center from the axis of the web. A formula for "e" was given which applies to symmetrical channels of uniform thickness. In the present report this expression for "e" will be simplified and a more general expression will be derived for "e" for symmetrical channels with web thickness differing from flange thickness. Furthermore, …

Cornell University School Of Civil Engineering Tests On Light Beams Of Cold-Formed Steel, Cornell University School Of Civil Engineering

CCFSS Library (1939 - present)

I SCOPE OF THIS REPORT It has been mentioned repeatedly in previous Reports that the spot welds in the web joining the two parts of the beam tended to pull apart at the supports. It is therefore obvious that, in order to properly design such beams, this fact must be taken into consideration. The present report undertakes to give an analysis of this behavior and to stipulate certain requirements with respect to these welds (strength, spacing) which have to be met in order that such failures may be excluded. The present analysis pertains only to beams made up of two …
