토크

정의

힘의 회전 등가물로, 가해진 힘에 회전축까지의 수직 거리를 곱한 값이며 N·m 또는 lb·ft로 측정한다.

설명

A 20 N force applied 0.5 m from a bolt produces 10 N·m of torque. Car engine torque—typically 200–600 N·m for passenger vehicles—determines acceleration feel at low speeds, while horsepower governs top-end performance. Torque wrenches allow fasteners to be tightened to precise specifications, preventing both under-tightening (joint failure) and over-tightening (stripped threads).
