Introduction Stress Strain Curve Strength Of Materials

The unit of the load is kgf and that of the area is square meter (i.e. m 2). so the unit of stress becomes kgf m 2. and if the area is expressed in square centimeter than the unit of stress is kgf cm 2. in si system of units. the load is measured in newton and the area measured in m 2. so the unit of stress is n m 2.

Units of stress. since the unit of load is n and the unit of cross section area is m 2 or cm 2 or mm 2. so the si unit of stress is n m 2 or n cm 2 or n mm 2. generally in the numerical problems we use n m 2 or n mm 2. relation between units of stress: 1 mn m 2 = 10 6 n m 2 = 10 2 n cm 2. Strength of materials, also called mechanics of materials, deals with the behavior of solid objects subject to stresses and strains.the theory began with the consideration of the behavior of one and two dimensional members of structures, whose states of stress can be approximated as two dimensional, and was then generalized to three dimensions to develop a more complete theory of the elastic. Cross – sectional area of a block of material is subject to a distribution of forces which are parallel, rather than normal, to the area concerned. such forces are associated with a shearing of the material, and are referred to as shear forces. the resulting force per unit area is known as shear stress. the resulting force intensities are.

Stress & strain. when a force is applied to a structural member, that member will develop both stress and strain as a result of the force. stress is the force carried by the member per unit area, and typical units are lbf in 2 (psi) for us customary units and n m 2 (pa) for si units:.

Strength of materials basically considers the relationship between the external loads applied to a material and the resulting deformation or change in material dimensions. in designing structures and machines, it is important to consider these factors, in order that the material selected will have adequate strength to resist applied loads or.
