Book Synopsis Diagonal Tension in Curved Webs by : Paul Kuhn
Download or read book Diagonal Tension in Curved Webs written by Paul Kuhn and published by . This book was released on 1947 with total page 542 pages. Available in PDF, EPUB and Kindle. Book excerpt: The engineering theory of incomplete diagonal tension in plane webs presented in NACA TN No. 1364 is generalizd in order to make it applicable to curved webs. Comparisons are given between calculated and experimental results for a number of stiffened cylinders subjected to torsional loads. The results indicate that the theory predicts the stresses to about the same accuracy for curved webs as for plane webs. The failing stresses in the stringers in curved webs were predicted conservatively in all cases.

Download or read book Accelerations and Passenger Harness Loads Measured in Full-scale Light-airplane Crashes written by A. Martin Eiband and published by . This book was released on 1953 with total page 652 pages. Available in PDF, EPUB and Kindle. Book excerpt: Full-scale light-airplane crashes simulating stall-spin accidents were conducted to determine the decelerations to which occupants are exposed and the resulting harness forces encountered in this type of accident. Crashes at impact speeds from 42 to 60 miles per hour were studied. The airplanes used were of the familiar steel-tube, fabric-covered, tandem, two-seat type.
Book Synopsis Experimental Investigation of Velocity Distributions Downstream of Single Duct Bends by : John R. Weske
Download or read book Experimental Investigation of Velocity Distributions Downstream of Single Duct Bends written by John R. Weske and published by . This book was released on 1948 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results indicate that cross-sectional shape and aspect ratio are minor factors compared with radius ratio in affecting the velocity pattern. Variation of Reynolds number within the range of the tests had no appreciable effect on the velocity distribution in curved ducts.
Book Synopsis The Theory of Diffusion in Strained Systems by : Louis A. Girifalco
Download or read book The Theory of Diffusion in Strained Systems written by Louis A. Girifalco and published by . This book was released on 1959 with total page 1082 pages. Available in PDF, EPUB and Kindle. Book excerpt: A general theory of solid-state diffusion in strained systems is developed on a molecular-kinetic basis. The theory predicts that for simple strains the diffusion coefficient is an exponential function of the lattice parameter and that the rate of change of the diffusion coefficient with strain is linearly related to the interatomic forces. It has also been shown that for plastic flow the diffusion coefficient is a linear function of strain rate. All the conclusions are confirmed by the data available in the literature.

Book Synopsis The 1350 Degree Stress-rupture Properties of Two Wrought Alloys and Three Cast Alloys by : E. E. Reynolds
Download or read book The 1350 Degree Stress-rupture Properties of Two Wrought Alloys and Three Cast Alloys written by E. E. Reynolds and published by . This book was released on 1947 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rupture-test characteristics at 1350 degrees F of two wrought alloys in the solution-treated and aged condition, NR-82 (6059 modified-low carbon) and NR-84 (N-155 modified-low carbon), and three precision-cast alloys in aged condition, NR-71 (X-40), NR-87 (Co-Cr-Ni base-9Mo) and NR-90 (Co-Cr-Ni base-5Mo, 5W) are reported. The properties are shown to compare favorably with those of the strongeest similar alloys previously investigated. A correlation of NACA and OSRD data is presented, showing the variation of ruture strengths with temperature for the alloys between 1350 degrees and 2000 degrees F.
Book Synopsis Cold-Formed Steel Design by : Wei-Wen Yu
Download or read book Cold-Formed Steel Design written by Wei-Wen Yu and published by John Wiley & Sons. This book was released on 2019-09-16 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: Provides the latest AISI North American specifications for cold-formed steel design Hailed by professionals around the world as the definitive text on the design of cold-formed steel, this book provides descriptions of the construction and structural behavior of cold-formed steel members and connections from both theoretical and experimental points of view. Updated to reflect the 2016 AISI North American specification and 2015 North American framing standards, this all-new fifth edition offers readers a better understanding of the analysis and design of the thin-walled, cold-formed steel structures that have been widely used in building construction and other areas in recent years. Cold-Formed Steel Design, 5th Edition has been revised and reorganized to incorporate the Direct Strength Method. It discusses the reasons and justification for the various design provisions of the North American specification and framing design standards. It provides chapter coverage of: the types of steels and their most important mechanical properties; the fundamentals of buckling modes; commonly used terms; the design of flexural members, compression members and closed cylindrical tubes, and of beam–columns using ASD, LRFD, and LSD methods; shear diaphragms and shell roof structures; standard corrugated sheets; and more. Updated to the 2016 North American (AISI S100) design specification and 2015 North American (AISI S240) design standard Offers thorough coverage of ASD, LRFD, LSD, and DSM design methods Integrates DSM in the main body of design provisions Features a new section on Power-Actuated Fastener (PAF) Connections Provides new examples and explanations of design provisions Cold-Formed Steel Design, 5th Edition is not only instructive for students, but can serve as a major source of reference for structural engineers, researchers, architects, and construction managers.

Book Synopsis Stresses Around Rectangular Cutouts in Torsion Boxes by : Paul Kuhn
Download or read book Stresses Around Rectangular Cutouts in Torsion Boxes written by Paul Kuhn and published by . This book was released on 1953 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method is presented for calculating the stresses produced by rectangular cutouts of any size in torsion boxes. The problem is divided into a "box problem" and a "cover problem." The box problem is a special case of the general method of analyzing torsion boxes without cutouts. In the cover problem, simple shear-lag theory is used to obtain "key" stresses; the final distributions are obtained from these key stresses by means of simple rules or empirical distribution curves. Comparisons with the results from three series of tests in which the dimensions of the cutouts varied over a wide range are shown.

Book Synopsis Determination of the Elastic Constants of Airplane Tires by :
Download or read book Determination of the Elastic Constants of Airplane Tires written by and published by . This book was released on 1954 with total page 680 pages. Available in PDF, EPUB and Kindle. Book excerpt: For determination of the elastic constants of airplane tires which are required for the numerical calculations of the shimmy properties of nose and tail wheels, deformation measurements were carried out on four different tires. For this purpose, the tires were loaded in each case with a normal load and then with a lateral force, a tangential force, and a moment. Moreover, the weight and the mass moment of inertia about a vertical axis were determined for the various tires.
