Tensile stress refers to the stress experienced by a material when forces are applied that pull it apart, causing elongation. It occurs when a material is subjected to axial loads that act along its length, stretching the material. The formula for tensile stress is: tensile stress = force / cross-sectional area or σ = F...

Compressive stress occurs when a material is subjected to forces that push inward, attempting to shorten or crush it. It is the opposite of tensile stress and arises in components designed to bear loads that press against them, such as columns, struts, and machine frames. The formula for compressive stress is: compressive stress = force...

Shear stress occurs when forces act parallel to a material’s surface, causing adjacent layers to slide past each other. Unlike tensile and compressive stress, which act perpendicular to a surface, shear stress results from forces applied tangentially. The formula for shear stress is: shear stress = force / cross-sectional area or τ = F /...

Torsional stress occurs when a material is subjected to a twisting force, or torque, causing it to rotate about its axis. This type of stress is common in shafts, gears, and other rotating components where torque is transmitted. Torsional stress is a form of shear stress, as it results from forces acting tangentially along a...

Flexural stress, also known as bending stress, occurs when a material is subjected to a bending moment, causing it to experience both tension and compression. In a beam under bending, the material's outermost fibers experience the highest stress, with one side in tension and the opposite side in compression, while the neutral axis (centerline) remains...

Engineering stress and true stress are two ways of measuring stress in a material during deformation, particularly in tensile testing. The key difference lies in how the cross-sectional area of the specimen is considered in the calculation. Engineering Stress (Nominal Stress) is calculated by dividing the applied force by the original cross-sectional area of the...
