It means increasing the cross-sectional area does not always help in making the structure strong. An important analogy of this case can be given to punching failure of concrete slabs. For example, in flat slab design, engineers usually have problem with punching shear and the general solution ...
Cross-sectional analysis is not used solely for analyzing a company; it can be used to analyze many different aspects of business. For example, a study released on July 18, 2016, by the Tinbergen Institute Amsterdam (TIA) measured the factor timing ability of hedge fund managers. Factor timin...

In cross-sectional research, you observe variables without influencing them. Researchers in economics, psychology, medicine, epidemiology, and the other social sciences all make use of cross-sectional studies in their work. For example, epidemiologists who are interested in the current prevalence of a...
A cross-sectional photograph can be used to further evaluate the crimped termination when additional diagnostics are determined to be necessary. The cross-section should be used as a reference image for comparison to future cross-sections. This reference image should be made with new crimp tooling...
A cross-sectional study (also known as a cross-sectional analysis, transverse study, prevalence study) is a type of observational study that analyzes data from a population, or a representative subset, at a specific point in time. It examines the relationship between diseases (or other health-...

VABS by AnalySwift, is a general-purpose cross-sectional analysis tool for computing beam properties and recovering 3D stresses and strains of slender composite structures. The tool of choice for helicopter and wind turbine rotor blades, VABS is also a powerful tool for rigorous simulation of oth...
The behavior and analysis of thin-walled beams are governed by the shape of the beam cross section, which leads to such beams being classified as one of these: • Beams with closed cross-sectional contours (see Fig. 10.1) Sign in to download full-size image FIGURE 10.1. Composite thin-...
