Load is to be transported from one location to other location with the help of heavy vehicles, the load is placed on heavy vehicles with the help of crane or forklifts or conveyer belt, crane hook which bears the entire load. The weight of the load is related to dimensions and material of the hook.  The major part which is to be replaced as per load is crane hook, hook is subjected to pressure and bending stress. In the present work the crane hook of different cross sections is being analyzed on model of crane hook. The crane hook is modeled on the Solidworks and analysis using Ansys. From the structural analysis performed on crane hook the stress values based on the model and stress value modifications are found.

Stress And Deformation

Based on 150 seats BWB civil aircraft, an aluminum triple-bubble cabin model are built. By large deformation analysis, the triple-bubble cabin is indicated the bending stress theory of non-cylindrical fuselage in the internal pressure. Zero-order parameter optimization arithmetic is employed to optimize the sizes of skin, stringers, beams and ribs in the triple-bubble cabin. By restricting the maximum stress and deformation, a light triple-bubble cabin configuration is obtained. The structural analysis method on the aluminum triple-bubble cabin is reliable and applicable.

Spirillum serpens possesses a surface layer protein which exhibits a regular hexagonal packing of the morphological subunits. A morphological model of the structure of the protein has been proposed at a resolution of about 25 Å, in which the morphological unit might be described as having the appearance of a flared-out, hollow cylinder with six ÅspokesÅ at the flared end. In order to understand the detailed association of the macromolecules, it is necessary to do a high resolution structural analysis. Large, single layered arrays of the surface layer protein have been obtained for this purpose by means of extensive heating in high CaCl2, a procedure derived from that of Buckmire and Murray. Low dose, low temperature electron microscopy has been applied to the large arrays.As a first step, the samples were negatively stained with neutralized phosphotungstic acid, and the specimens were imaged at 40,000 magnification by use of a high resolution cold stage on a JE0L 100B. Low dose images were recorded with exposures of 7-9 electrons/Å2. The micrographs obtained (Fig. 1) were examined by use of optical diffraction (Fig. 2) to tell what areas were especially well ordered.

Low Ionic Strength

While DNA-dependent RNA polymerase represents one of the key enzymes involved in transcription and ultimately in gene expression in procaryotic and eucaryotic cells, little progress has been made towards elucidation of its 3-D structure at the molecular level over the past few years. This is mainly because to date no 3-D crystals suitable for X-ray diffraction analysis have been obtained with this rather large (MW ~500 kd) multi-subunit (α2ββ'ζ). As an alternative, we have been trying to form ordered arrays of RNA polymerase from E. coli suitable for structural analysis in the electron microscope combined with image processing. Here we report about helical polymers induced from holoenzyme (α2ββ'ζ) at low ionic strength with 5-7 mM MnCl2 (see Fig. 1a). The presence of the ζ-subunit (MW 86 kd) is required to form these polymers, since the core enzyme (α2ββ') does fail to assemble into such structures under these conditions.

Introduction: The analysis and interpretation of electron micrographs of cells and tissues, often requires the accurate extraction of structural networks, which either provide immediate 2D or 3D information, or from which the desired information can be inferred. The images of these structures contain lines and/or curves whose orientation, lengths, and intersections characterize the overall network.Some examples exist of studies that have been done in the analysis of networks of natural structures. In, Sebok and Roemer determine the complexity of nerve structures in an EM formed slide. Here the number of nodes that exist in the image describes how dense nerve fibers are in a particular region of the skin. Hildith proposes a network structural analysis algorithm for the automatic classification of chromosome spreads (type, relative size and orientation).
