Enter the total force applied to the wrench (N), the direction of force applied to the wrench (deg), and the length of the wrench (m) into the calculator to determine the Wrench Torque. 

Wrench Torque Formula

The following formula is used to calculate the Wrench Torque.

Tw = F * sin(af) * R

  • Where Tw is the Wrench Torque (N-m)
  • F is the total force applied to the wrench (N) 
  • af is the direction of force applied to the wrench (deg) 
  • R is the length of the wrench (m) 

How to Calculate Wrench Torque?

The following example problems outline how to calculate Wrench Torque.

Example Problem #1

  1. First, determine the total force applied to the wrench (N). In this example, the total force applied to the wrench (N) is determined to be 15 .
  2. Next, determine the direction of force applied to the wrench (deg). For this problem, the direction of force applied to the wrench (deg) is measured to be 45 .
  3. Next, determine the length of the wrench (m). In this case, the length of the wrench (m) is found to be .10.
  4. Finally, calculate the Wrench Torque using the formula above: 

Tw = F * sin(af) * R

Inserting the values from above and solving yields: 

Tw = 15 * sin(45deg) * .10 = 1.060 (N-m)


Example Problem #2

Using the same method as above, determine the variables required by the formula. For this example problem, these are:

total force applied to the wrench (N) = 16

direction of force applied to the wrench (deg) = 40

length of the wrench (m) = .75

Enter these given values into the calculator or above yields: 

Tw = 16 * sin(40deg) * .75 = 7.713 (N-m)
