Hi am rakesh i would like to get details on jbk das mechanics of material book download pdf ..My friend sandy said jbk das mechanics of material book download pdf will be available here and now i am living at ......... and i last studied in the college maratha mandal of puc......... and now am doing engineering in same college ....i need help on MECHANICS OF MATERIAL pdf

In materials mechanics, the resistance of a material is its ability to withstand an applied load without flaws or plastic deformations. The field of material strength deals with the forces and deformations that result from its action on a material. A load applied to a mechanical member will induce internal forces within the member called stresses when those forces are expressed in a unit. The stresses that act on the material cause the deformation of the material in several ways, including its complete breakage. The deformation of the material is called tension when those deformations are also placed in a unit. The applied loads can be axial (tensile or compressive) or rotary (resistance to shear). The tensions and tensions that develop within a mechanical member must be calculated to evaluate the load capacity of that member. This requires a complete description of the geometry of the member, its restrictions, the loads applied to the member and the properties of the material of which the member is composed. With a complete description of the load and the geometry of the member, the tension state and the state of tension can be calculated at any point within the member. Once the tension and tension state inside the member is known, the resistance (load capacity) of that member, its deformations (stiffness qualities) and its stability (ability to maintain its original configuration) can be calculated. The calculated stresses can then be compared with some measure of the strength of the member, such as its material yield or its ultimate strength. The calculated deflection of the member can be compared to a deflection criterion that is based on the member's use. The calculated buckling load of the member can be compared with the applied load. The calculated stiffness and the mass distribution of the limb can be used to calculate the dynamic response of the limb and then compared with the acoustic environment in which it will be used. The strength of the material refers to the point in the engineering stress-strain curve (yield stress) beyond which the material undergoes deformations that will not fully reverse when the load is removed and as a result the member will have a permanent deflection. The maximum resistance refers to the point in the stress-strain curve of engineering corresponding to the stress produced by the fracture.
