As a Chinese player, I come into some confusion when I see the translation of everything about "stress". In this mod's wiki, it seems that stress is like torque in reality. But the translation tries to convey that stress is "Stress (mechanics)", the same as what it means in "bridge stress". So I wonder if the CN translation should be fixed or be kept as it is. If former, I can contact to the translator and tell him about this.

Stress is the correct term. Calling it torque would imply some physical principles create does not follow with its simplified mechanics.
If you'd like to make any changes to the translation, feel free to contact the author or just open a new pull request yourself. Thanks!
