Mechanics of materials

Mechanics of Materials Science and Engineering is part of the civil laws of physics that studies about the behavior of a material when loaded, especially the problem of the forces that occur in these materials and their derivatives.Definitions Voltage is the force per unit area, where the style is meant here is the styles, the style of which occurred within a material due to the resistance of materials to compensate for external forces. Generally, the force acting on the broad infinitely small on a piece, will consist of an assortment of magnitude and direction.In Mechanics of materials, the intensity of the forces should be determined dalarn in various parts of the piece, as the resistance of the deformation, while the ability of materials to withstand the force is dependent on the intensity of this.In general, the intensity of this style is trending oblique to the field pieces. Usually in the calculation of the intensity of the force is decomposed into perpendicular and parallel pieces. The intensity of the perpendicular style called Normal Tension (Normal Stress) is denoted by s (read: Sigma). Meanwhile, the other stress components parallel to the field pieces called Voltage Slide (Shearing Stress) and is denoted by t (read: Tau).In addition to the above stresses known also what is called Voltage Bending, arising due to bending moment (Bending Moment).Normal voltage.An axial forces pose an equal pull on the rod, because it is said to Pull rods (Tension). P works on the right end of the rod. At the left end of the working styles of action. These forces are continuously distributed throughout the cross section of the trunk and called Normal Tension (σn). Normal voltage is defined by:Flexural stress (σl).Bending stress due to moment arising from the force and external load.Voltage combination.Combined voltage is the voltage that occurs due to the normal force and moment yan style or expense arising from outside. In these conditions the resultant stresses that work can be obtained by downloading the voltage superposisikan normal stresses that occur are caused by axial force (P) and bending moment (M).Voltage Slide.Transverse force perpendicular D work pieces. Styles that work in the field of cuts will be distributed evenly across the cross section of the rod, and is called the Voltage Slide (τ).τ = DS / bIWhere:D = style latitudes.S = static moment of pieces that were reviewed.b = width of pieces that were reviewed.I = Inertia pieces.
