1.
critical speed; the maximum speed something can sustain
The upper speed at which a vehicle, machine, or moving body can still operate safely or stably; beyond it, control or structural integrity is lost. A technical term in physics and engineering.
限界速度を超えた。
It exceeded the critical speed.
この機械には限界速度がある。
This machine has a maximum operating speed.
カーブで限界速度を超えると、車は制御を失う恐れがある。
If you exceed the critical speed on a curve, the car may lose control.
Formed from 限界 (limit) plus 速度 (speed). It names the speed beyond which safe or stable operation breaks down, and is mostly a technical term.
COMMON COLLOCATIONS:
- 限界速度を超える: to exceed the critical speed
- 限界速度に達する: to reach the limiting speed
SIMILAR WORDS:
- 制限速度: speed limit — the legally set maximum for a road, not a physical limit
- 最高速度: top speed — the fastest a vehicle can go, without the safety nuance
