First, pinyin: zhāng lì √.

Secondly, explain:

1. One of the two balancing forces leading to elongation.

2. Stress generated when an elastic object is elongated

3. In the field of philosophy, it is particularly contradictory or incompatible.

4. Tension of violin strings

5. Tension and elasticity from the inside out. Boxers' muscles are more tense.

Third, the application example:

In literary criticism, there is often such an evaluation: the article is written easily. In other words, writing articles should be tight, loose, sparse and dense, and articles with good rhythm are pleasing to the eye. "Zhang" here means nervous. In physics, it often refers to a kind of traction generated inside an object after it is pulled. Literary direction refers to the author's mastery of the plot content of the article, which can be accepted and released, so that the rhythm of the article is appropriate, not procrastinating, like the opening and closing of a bow, not dull and not exaggerated, just right.

Fourth, physical terms:

1, under tension, mutual traction exists on both sides of any cross section inside the object.

2. Please note that tension and liquid surface tension are not the same concept. The surface tension of water is intermolecular attraction, which tries to keep the surface area of liquid to a minimum, and among all shapes, only the spherical surface area is the smallest. Therefore, the liquid in weightlessness is spherical.

3. Crustal movement produces pressure and tension, and pressure is common in convergent plates, such as the collision between the Indian Ocean plate (the Indian continent is in front) and the Eurasian plate. Tension is common in separated plates, such as submarine spreading, Red Sea Rift and East Africa Rift. Pressure and tension are complementary in crustal movement. For example, many inland fault zones are not caused by the tension of separating plates, but by converging plates. For example, the pressure generated by the subduction of ocean plates under continental plates will inevitably lead to tensile cracks in weak links. For example, in the transition zone from Chengdu Plain to Qinghai-Tibet Plateau, the average crust transition from 35km to 65km in Longmenshan fault zone (called stress concentration point in material mechanics).
