Find the point of application of force and the point around the body. Measure the distance between them. This will be the moment arm. Determine the direction of the force at the point of application, using a dynamometer. Using a protractor, find the acute angle between the line.
Find the torque by multiplying the value of the force and the acute angle between them (M = F • l • sin (α)). If the force is perpendicular to the point of her shoulder, then sin (α) = 1, and under these conditions develops maximum torque.
Engine performing torque is the algebraic sum of many moments of the forces acting on the various parts of the engine. Therefore, the easiest option is to find out the torque of the technical documentation that came with your device.
If such information is not available to measure the frequency of a tachometer motor shaft speed in revolutions per minute, measure the power of the engine, or learn from the documentation, expressing it in kilowatts.

The easiest way to find the number of horsepower in the engine of the car is to look at data sheet of the machine. If the registration card is missing, you can go to the directory corresponding to the automaker, which tells the power of all cars produced by a given manufacturer. If the power is shown in kilowatts, you can convert it by using the formula: power in kilowatts multiplied by 1.35962.
