What Is Tension Force?

Tension, physics term. When an object is subjected to a tensile force, the mutual traction forces existing in the interior of the object and perpendicular to the contact surfaces of the two adjacent parts.

Mutual traction on both sides of any section inside an object when subjected to a tensile force.

It is important to note that tension and liquid surface tension are not the same concept. 'Surface tension of water' is the gravitational intermolecular force that tries to keep the surface area of the liquid to a minimum, and of all shapes, only the spherical surface area is the smallest. Therefore, the liquid in a weightless state is spherical.

Crustal movement generates pressure and tension. Pressure is often found in convergent plates, such as the collision between the Indian Ocean plate (with the Indian continent at the front end) and the Eurasian plate. Tension is common in discrete plates, such as seafloor expansion, the Red Sea Rift, and the East African Great Rift. Pressure and tension are complementary in crustal movement. For example, many inland fault zones are not caused by the tension of the separate plates, but rather are the convergent plates. For example, the pressure caused by the subduction of the oceanic plate below the continental plate causes the continental block to bulge, and the bulge will inevitably produce weak links.

For example, the Chengdu Plain to the Qinghai-Tibet Plateau transition zone, the crustal transition from an average of 35 kilometers to 65 kilometers (called stress concentration point in material mechanics) Longmenshan fault zone.
