查询词典 physics

Torque is the torque in the physics of small, equal to the product of force and lever arm, the international unit is Nm Nm, In addition we can also see kgm, lb-ft of torque of this unit, as a result of G = mg, when g = 9.8 when, 1kg = 9.8N, so 1kgm = 9.8Nm, and the foot-pound is lb-ft of torque imperial units, 1lb = 0.4536kg; 1ft = 0.3048m, can be calculated 1lb-ft = 0.13826kgm.

扭矩在物理学中就是力矩的大小，等于力和力臂的乘积，国际单位是牛米Nm，此外我们还可以看见kgm、lb-ft这样的扭矩单位，由于G=mg，当g=9.8的时候，1kg＝9.8N，所以1kgm＝9.8Nm，而磅尺lb-ft则是英制的扭矩单位，1lb=0.4536kg；1ft=0.3048m，可以算出1lb-ft＝0.13826kgm。
