Mehaanilised pinged (mechanical stresses) refer to the internal forces that exist within a solid material or structure as a result of external forces or constraints. When an external force is applied to an object, such as pulling, pushing, or bending, the material deforms. This deformation creates internal resisting forces that counteract the applied force. These internal forces are what we call mechanical stresses.

There are several types of mechanical stresses. Tensile stress occurs when a material is pulled or stretched. Compressive stress arises when a material is pushed or squeezed. Shear stress is experienced when forces act parallel to a surface, tending to cause one part of the material to slide over another. Bending stress involves a combination of tensile and compressive stresses across the cross-section of a beam or other structural element.

Understanding mechanical stresses is crucial in engineering and material science. It allows for the design of structures and components that can withstand expected loads without failing. When stresses within a material exceed its strength, it can lead to deformation, yielding, or fracture. Material properties like tensile strength, yield strength, and Young's modulus are used to quantify a material's response to stress and its ability to resist failure. Analyzing mechanical stresses helps ensure the safety, reliability, and longevity of manufactured goods and infrastructure.
