Torque is a special torque that makes an object rotate. The torque of the engine refers to the torque output by the engine from the crankshaft end. Under the condition of constant power, it is inversely proportional to the engine speed. The faster the engine speed, the smaller the torque, and vice versa, which reflects the load capacity of the car in a certain range. The external torque is called torque or external couple moment, and the internal torque is called internal couple moment or torque.

Torque (also called torque) is a special kind of torque in physics, which is equal to the product of force and arm. The international unit is n meters. In addition, we can see torque units such as kilogram meters and pound feet. Because G=mg, when g=9.8, the gravity of 1 kg is 9.8N, so 1kg. It can be calculated that 1ft=0.3048m,1lb-ft = 0.13826kgm. In people's daily expression, torque is often called torsion (in physics, these are two different concepts).

I hope it can help you solve the problem.
