The meaning of torque

The material generated during torsional deformation force is applied, the unit N · m. When torsional rigidity or torsional modulus and other mechanical measuring material when to reverse the dynamic mechanical properties of materials testing methods, are required torque applied to the specimen. Especially in many dynamic mechanical measuring instruments, as relatively easy to achieve free oscillations or forced oscillation of torque applied to the form, so the use is more widespread. Such as Wiggler analyzers, twisted braid analyzers, such as rotational rheometer torque is applied to the sample.

The so-called Torque is an object of the reaction by the axial force and torsion, commonly used to measure torque wrench, the unit is Nm. Common torsion
Force objects have screw nut drive shaft and so on.

The so-called "torque" in physics should be called "torque" because the results of many rumors, we say that a "torque", also handed down since then, as the guide straight. The concept of torque from the elementary school's "lever principle" to explain over the definition of a "vertical force multiplied by the distance from the center of rotation", metric units of Newton - meters (Nm), divided by the acceleration due to gravity 9.8m / sec2 After that, the unit can be converted to the people familiar with the kilogram - meter (kg-m). Imperial units, compared with pounds - feet (lb-ft), in the United States is more common car catalog, to be converted into metric, as long as the digital divide lb-ft to 7.22.

Torque units and conversion

"Torque" in physics should be called "torque", "turning moment" is the object by the moment an object rotation direction of the cut to the force generated when, commonly imported products are torque wrench (now also in the domestic setting factory assembly), torque approved (torque screwdriver), torque meter, electric screwdriver torque tester, cap torque tester to measure. Because the result of many rumors, we say to "Torque."
Simply torque = force multiplied by the arm. For example, arm (i.e. wrench) long 1M, 100N of force is applied, the torque is 100N.m. The concept of torque from the elementary school "lever principle" to explain too, is defined as "the force multiplied by the vertical distance between the center of rotation." After the international common metric units of Nm Nm, divided by the acceleration due to gravity 9.8m / sec2, units can be converted into people familiar kgf. M kgf.m or kgf. Cm kgfNaN. Imperial units, compared with pounds. Ft lb.ft, to convert to metric, as long as the digital divide 7.22 lb.ft can.
