Book Description
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 Description
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 Description
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 Description
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 Description
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.
