Stress and Strain is the first topic in Strength of Materials which consist of various types of stresses, strains and different properties of materials which are important while working on them. As particular stress generally holds true only at a point, therefore it is defined mathematically as. If the force applied are perpendicular or normal to areas concerned, then these are termed as normal stresses. The normal stresses can be either tensile or compressive depending upon the direction of the load. Such forces are associated with a shearing of the material, are known as shear forces. The stress produced by these forces are known as shear stresses.

3. (a). An elastic moduli is a ratio of stress to strain; elastic limit is the maximum stress that exists before a material flows plastically; strength is the maximum.
