关于此计算器
Torque is the rotational equivalent of force — the twisting effect a force has about a pivot. It is τ = F × r × sin(θ), where F is the applied force, r is the lever arm (distance from the pivot) and θ is the angle between the force and the arm. Only the component of force perpendicular to the lever produces rotation, so torque is greatest when the force is applied at a right angle (θ = 90°), reducing to the familiar τ = F × r. The SI unit is the newton-metre (N·m); this calculator also converts to pound-feet (1 N·m ≈ 0.7376 lb·ft).
As a worked example, pushing with 100 N at the end of a 0.5 m wrench, perpendicular to the handle, produces τ = 100 × 0.5 × sin(90°) = 50 N·m. Angle the same push at 30° to the handle and it drops to 100 × 0.5 × 0.5 = 25 N·m, because only half the force now acts crossways. This is why a longer wrench or a straight-on pull loosens a stubborn bolt more easily — you multiply either the lever arm or the effective force.
If you enter a rotational speed, the calculator also returns the mechanical power, P = τ × ω, where the angular speed ω = rpm × 2π / 60 in radians per second. The same torque delivers more power the faster it turns, which is the link between an engine’s torque and its horsepower. Torque calculations are essential for tightening fasteners to spec, sizing motors and gearboxes, designing levers and wrenches, and analysing any rotating machinery.
经常问到的问题
硬化公式是什么?
等于杠杆的倍数乘以角度的正弦, =F × r × sin(). 以牛顿米( n.m) 测量。
为什么角度重要?
只有与杠杆垂直的力组件产生旋转。 在90度时,所有力都有效;在0度(手臂上直冲),扭矩为零。
力和力是如何关联的?
机械力是硬力乘以角速,P= ×,其中 = rpm × 2 / 60。 同样的墨水力能以旋转速度越快,动力就越大。
火力和武力有什么区别?
力是直线推力或拉动牛顿;托克是其旋转效应,它指一个牛顿米的枢轴,取决于力量和它作用距离。 同样的力在更长的杠杆臂上给予更大的扭力。
我如何将牛顿米转换成磅脚?
Multiply N·m by 0.7376. So 50 N·m is about 36.9 lb·ft. The calculator shows both units, which is handy since torque specs are quoted in N·m in most of the world and lb·ft in the US.
我怎样才能在螺栓上 得到更多的火力?
增加杠杆臂或力,或将力力用在右角。扳手的长度是扳手的两倍,或者直拉而不是角度拉,两者都为同样的努力而增加力力,这就是断开棒工作的原因。
角真的会改变 扭扭的那么大吗?
是的,带有罪的托克比例,因此,杠杆(0°)的一股力量完全不能旋转,30°给予最大半的重量,只有直角推(90°)才能提供全部F×r。 将力的正方保持在手臂上,效果最大。
