 # How Do I Know How Much Torque I Need?

## How much torque does a car need?

Very heavy duty automotive fasteners require between 200 and 1,000 ft.

lbs of torque, or even higher amounts.

Applications include camshaft sprockets and harmonic balancers.

Many off-road vehicles or performance racing vehicles will require torque applications in this range as well..

## How much torque do you need for an impact wrench?

The average torque for 3/4 inch impact wrench is about 1200 ft/lbs. As stated before, it is more than enough for even the most substantial tasks.

## How much torque is needed to move a person?

Even at 0.020 (more likely for little scooter wheels), that’s only 3.2 lbs. The force needed to accelerate is F=MA; a moderate acceleration rate is about 0.1g, which means that you’ll need 16 lbs of force to achieve that.

## Can you have negative torque?

Technically, torque is also a vector – but that might be a little too much at this point. … Oh, torque can be positive or negative. Let us say that a positive torque would make a stationary object rotate counter clockwise and a negative torque would make it rotate clockwise.

## How much torque does a 1 hp motor have?

The definition of 1 Horsepower is displacing 1 lb. 33,000 ft. in one minute or 33,000 lb-ft / minute.

## How much weight can a 1 hp motor lift?

Most engines use horsepower to describe how much work they can do in a given amount of time. The constant 1 horsepower equals 550 foot-pounds per second. In other words, 1 horsepower is the amount of work required to move a load of 550 pounds over 1 foot, in 1 second.

## How do you calculate torque needed?

Calculation for Required Torque ( TM ) The required torque is calculated by multiplying the sum of load torque and acceleration torque by the safety factor.

## How much torque do lug nuts need?

And when you look at that, and realize that the average torque required on a lug nut, to hold the wheel on, is 80 to 90 ft-lbs, well you can imagine how over-tightened some of these lug nuts are. Now that’s a problem because it almost guarantees warped brake rotors.

## How much torque does a 1/2 impact have?

The M18 FUEL™ 1/2″ High Torque Impact Wrench with Friction Ring Kit features the most powerful cordless wrench in its class, delivering up to 700 ft-lbs of maximum fastening torque, 1,100 ft-lbs of nut-busting torque and up to 2X more runtime.

## How much torque does a 1/2 Air Impact have?

The 1/2 inch air impact gun can deliver up to 1,350 foot/pounds of loosening torque (930 foot/pound max torque) while remaining light enough that you’ll experience minimal fatigue.

## Can you set the torque on an impact wrench?

Currently, none of the cordless impact wrenches will allow you to adjust the torque to those exact settings. (An air impact wrench won’t either for that matter.) Basically it is another “socket” that won’t let the tool torque anymore than the ft/lbs you set it for. …

## How much torque is required to lift a weight?

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.

## How much torque is required for tightening the cylinder head?

If an engine produces 1,500 pounds of pressure and the cylinder head has 8 bolts, then each bolt must be tightened to 187 foot-pounds of torque to secure the cylinder head to the block.
