HomeStrength of materials Define Stress and also write their types? byPratik kamal -February 12, 2022 0 StressWhen a force acts on a body tending to produce deformation, a resistance is developed to this external force application.Definition: It is the Internal resistance to the externally applied force.. It is denoted by (σ). Stress (σ)= Force/Area (fig.1).. Pascal = 1 N / m².. Commonly stress is reported in terms of mega Pascals (MPA).MPA=10Types of stresses1. Axial stressesCompressive stressCompression results when the body is subjected to two sets of forces directed towards each other in the same straight line. (fig.2)Tensile stressTension results in a body when it is subjected to two sets of forces directed away from each other in the same straight line. (fig.2)Types of axial stresses• Axial Compressive. Tensile2. Non axial stressesShear stressShear is the result of two sets of forces directed towards each other but not in the same straight line (fig.3)TorsionIt results from the twisting of the body. (fig.3)BendingIt results by applying bending movement.(fig.3)Types of non axial stresses• Non AxialShearTorsionBending Tags: Strength of materials Facebook Twitter
