Enter your login details below. The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. To calculate the five year Impact Factor, citations are counted in 2016 to engineering mechanics problems with solutions pdf previous five years and divided by the source items published in the previous five years.

SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field. SJR is a prestige metric based on the idea that not all citations are the same. This application allows readers to interactively explore MATLAB figures submitted with the article, and to download the original data files. This application lets readers explore data and other quantitative results submitted with the article, providing insights into and access to data that is otherwise buried in plots.

Since ancient times humans have been consciously aware of stress inside materials. Stress is defined as the force across a “small” boundary per unit area of that boundary, for all orientations of the boundary. Because mechanical stresses easily exceed a million Pascals, MPa, which stands for megapascal, is a common unit of stress.

The cracks are the result of brief but intense stress created when the semi-molten piece is briefly dipped in water. Stress in a material body may be due to multiple physical causes, including external influences and internal physical processes. However, if the deformation is changing with time, even in fluids there will usually be some viscous stress, opposing that change. Idealized stress in a straight bar with uniform cross-section. This analysis assumes the stress is evenly distributed over the entire cross-section. In practice, depending on how the bar is attached at the ends and how it was manufactured, this assumption may not be valid.

Normal stress occurs in many other situations besides axial tension and compression. Shear stress in a horizontal bar loaded by two offset blocks. However, that average is often sufficient for practical purposes. In that case, the shear stress on each cross-section is parallel to the cross-section, but oriented tangentially relative to the axis, and increases with distance from the axis. Another simple type of stress occurs when the material body is under equal compression or tension in all directions. In these situations, the stress across any imaginary internal surface turns out to be equal in magnitude and always directed perpendicularly to the surface independently of the surface’s orientation. Gases by definition cannot withstand tensile stresses, but some liquids may withstand surprisingly large amounts of isotropic tensile stress under some circumstances.
