Mechanical stress and strain

WebThe Stress/Strain Curve is the relationship between the magnitude of applied stress on a material and the resulting strain (or elongation) caused to the material. Units and Symbols:-Stress is denoted by the lowercase Greek symbol, σ (pronounced 'sigma'). It is an applied force (Newtons, or N) over a given area (millimeters squared, or mm^2). WebHere the property of mechanical stress and strain plays an important role. It helps in determining whether the object can withstand these types of loads. Stress: It is the force applied to an object which is divided in terms of its cross-sectional area. σ …
