# Quick Answer: How is engine torque calculated?

Contents

The formula for figuring out torque is torque = horsepower of the engine x 5252, which is then divided by the RPMs. The problem with torque, however, is that it is measured in two different places: directly from the engine and to the drive wheels. … The calculation of torque of the engine is a lot easier to determine.

## How do you calculate torque on a car?

To calculate load torque, multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r). If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x 0.05 m = 1 Nm.

## Is it better to have more torque or horsepower?

Torque, simply, is the ability of a vehicle to perform work — specifically, the twisting force applied by the crankshaft. Horsepower is how rapidly the vehicle can perform that work. … Because there is generally a limit on how fast you can spin an engine, having higher torque allows for greater horsepower at lower rpms.

## How much torque is required to move a vehicle?

so rotational speed = Power / torque = 50,000 / 160 = 312.5 rad/s = 2984 rpm. Therefore a 50 kw motor, running at almost 3,000 rpm and producing a torque of 160 Nm, can accelerate a 200 kg vehicle at 4g up to a speed of 14 mph providing the vehicle is fitted with a suitable traction system.

## Does torque make a car faster?

Both horsepower and torque can affect the speed of a vehicle. Torque can help a vehicle accelerate to a higher speed quickly, whereas horsepower can help a vehicle improve its top speed.

## How much torque is enough for a car?

The lug nuts that attach the wheels to your car typically need to be tightened to about 100lb. -ft of torque — meaning the operator must apply 100 pounds of force to the end of a foot-long wrench.

## Can a torque be balanced by a single force?

No, torque can not be balanced by the single force. It can be balanced by the two forces, one tries to rotate the body in clockwise direction and other tries to rotate the body in anti clockwise direction. so no torque will be acting on the body.
