nyomásfeszültséget

Nyomásfeszültség, a Hungarian term, translates to "compressive stress" in English. It is a fundamental concept in physics and engineering, referring to the internal forces that particles within a material exert on each other when subjected to an external force that tends to push them together. When a material is under compressive stress, its volume typically decreases.

This type of stress arises when forces are applied perpendicularly to a surface and directed inwards. Common examples include the stress experienced by a column supporting a building, the pressure exerted on a submerged object, or the force that causes a spring to compress. The magnitude of nyomásfeszültség is calculated as the force applied divided by the cross-sectional area over which the force is distributed.

Understanding compressive stress is crucial for designing structures and components that can withstand such loads without deforming or failing. Materials have varying capacities to resist compressive stress, a property known as compressive strength. Brittle materials, like concrete, tend to fracture under high compressive stress, while ductile materials, like metals, may undergo plastic deformation before failure. The study of nyomásfeszültség is essential in fields such as civil engineering, mechanical engineering, and materials science to ensure safety and efficiency in design and construction.
