Available in PDF, EPUB and Kindle. Book excerpt: A method for calculating structural loads in a rocket engine-actuator-vehicle system is developed. The engine is attached to the vehicle by a universal-type gimbal joint and by two actuators. The engine is assumed to be a rigid body. Either the actuator loads or the engine angular acceleration is assumed to be known with a calculation of the other required. A set of algebraic equations is developed from which the unknown actuator loads or angular acceleration and the forces and moments at the gimbal point can be calculated . I.

This book was released on 1976 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes solutions to a class of dynamic elastoplastic problems that model some of the salient features of the response of hardened underground facilities in rock. The theoretical model consisted of multilayered concentric cylinders of elastoplastic materials with time-dependent loads applied to the exterior boundary. Each element in the cross section was assumed to be incompressible and its yield governed by a Mohr-Coulomb failure criterion. The number of elements within the cross section was not limited. Solutions of the theoretical model were cast in the general form normally used in structural dynamics: Mass x Acceleration = External applied load - Internal resistance. The resulting equations can be quickly and inexpensively evaluated on a digital computer. To extend the range of validity of the exact theory, a first-order correction factor was developed to account for the compressibility of the materials, and a simple method to treat backpacked structures was introduced. The theory was verified by comparing calculated values with experimental measurements from small-scale static and explosively driven tunnel collapse studies. Good agreement was noted for all cases considered. (Author).

This book was released on 2023-07-10 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aim: Durable reconstruction of the abdominal wall needs to be assessed in a lifelike experimental setting and consider the reconstructed abdominal wall as a coherent compound. Our aim was to evaluate broader possibilities in preclinical testing and to deepen the understanding of the biomechanical influences. Methods: We developed a test bench that allows studying a compound under cyclic, repetitive loads. Pulse loads transmit energy to the abdominal wall repeatedly. The amount of energy is related to the load characteristics. We used porcine bellies with a round central (5 cm) defect. They were bridged in a sublay position with Cicat Dynamesh®. Further defects, located in an additional incision, were sutured in a standardized small-bite technique. We varied the number of loads, the maximum peak pressure, the pressure plateau length, and the impact area size. Results: Increasing the peak pressure by 30 mmHg lowers the durability by about 20 %. Prolonging the plateau phase led to a significant durability decrease. During the first 100 dynamic intermittent strain (DIS) impacts, the major tissue deformation and the majority of failures occur. Beyond the 425th DIS impact, about 10 % more failures occur. Increasing elongation and deformation of the tissue raise the likelihood of failure. Conclusion: If the compound does not establish a strain-stable condition during the period of plastic deformation, failure occurs. The outcome does not only depend on the reconstruction technique but also on the external influences acting on the abdominal wall compound. Considering the biomechanical reality is important for open and minimally invasive abdominal wall reconstruction.

Book excerpt: Summary: Tests were made in the Langley impact basin to determine the relationship between impact normal acceleration and flight-path angle for seaplanes landing on smooth water. The tests were made at both high and low forward speeds with the model at 3° trim. The model had a dead-rise angle of 22 1/2° and, with the drop linkage, weighed 1100 pounds.

Available in PDF, EPUB and Kindle. Book excerpt: These 10 Games Lessons are designed to motivate children to listen attentively, develop positive attitudes and understand rules. Children will develop the skills of travelling, including chasing, fleeing and dodging; interact with others and use small apparatus to develop the skills required for more formal team games and sport when they are older. Each lesson includes lesson objectives, a list of resources, instructions for games, a warm-up activity, and an introductory activity. The skill building part of the lesson enables them to experiment and build upon their skills. There is a cool-down activity as well as assessment cues. There are also suggestions for extension activities and where appropriate ICT opportunities which include web links.

Book excerpt: This book summarizes the latest advances in understanding chloride ingress and steel corrosion in concrete under service loads. Unlike the existing literature, it focuses specifically on the effect of service loads on chloride-induced durability issues in reinforced concrete structures. It discusses how service loads affect the moisture and chloride penetration rate, corrosion kinetics and rust distribution, as well as the structural performance of concrete components (e.g. beams and columns) in a systematic and hierarchical way. Given its scope, the book is chiefly intended for researchers and industry practitioners in structural engineering, particularly those whose work involves the durability design of concrete structures.

Book excerpt: From the Pulitzer Prize and T.S. Eliot Prize for Poetry winner comes a beautifully realized collection of poems about childhood, love, marriage, children, and honoring the dead. Larry Lewis say, “The Dead and the Living is an unignorable book, something truly rare. The feeling behind it is painful, but exquisitely so. Pain made into art or what, in another time, people called ‘beauty.’” It is an achievement of a poet writing in the full measure of her powers.
