noun
tensile strength
Technical term used in materials science and engineering to describe the maximum stress a material can withstand while being stretched before breaking.
この鋼材の抗張力は非常に高い。
The tensile strength of this steel material is very high.
Compound of 抗 (resistance) + 張 (stretch) + 力 (strength), literally 'resistance-stretch strength'. The exact historical derivation is uncertain; the spelling is conventionally associated with the meaning.
