What is the torque tolerance of a wrench?
Torque (Torque, also known as torque) in physics is a special moment, is the product of the force and force arm, the international unit is Nm nm, also can see the KGM lb-ft, such as G=mg, torque, when g=9.8 1kg, the weight is 9.8N, so 1kgm= 9.8Nm, while the pound feet lb-ft is the imperial torque unit, 1lb=0.4536kg; 1ft=0.3048m, 1lb-ft=0.13826kgm can be calculated. In everyday expression, torque is often referred to as torque (in physics, these are 2 different concepts). For example, the torque of the 8 generation Civic 1.8 is 173.5Nm@4300rpm, which means that the output torque of the engine at 4300 revolutions per minute is 173.5Nm. How can the force of 173.5N drive 1 tons of cars? In fact, the engine torque will be magnified (at the same time reduce the speed), this will depend on the transmission, the final transmission and the tire. The release of the first engine torque through the transmission "adjustable" to end transmission torque amplification (for further amplification in the year-end party) (at the same time, to further reduce the speed) finally released the driving force of tire. If a car 1 speed gear ratio (the number of teeth of the gear ratio, is the essence of gear radius ratio) is 3, year-end party 4, tire radius of 0.3 meters, the original torque is 200Nm, the last in the axle torque to 200 x 3 x 4=2400Nm, divided by the tire radius of 0.3 meters, friction the tire and the ground part is 2400Nm/0.3m=8000N, that is the driving force of 800 kg, which is enough to drive a car.
Torque is a special torque that causes an object to turn. The engine torque is the torque that the engine produces from the crankshaft end. Under the condition of fixed power, it is inversely related to the engine speed. The faster the speed, the smaller the torque, the greater the reverse, which reflects the car's load capacity in a certain range. External torque is called torque, or external torque, and internal forces are called torque or torque.
Test / calculate the torque of the adjustable wrench: torque = load (kg) * local gravity acceleration * distance (meter).
