Enter the forces (N), the angles (degrees), and the radius (m) into the calculator to determine the Net Torque. 

Net Torque Formula

The following formula is used to calculate the Net Torque.

Tnet = ∑ f*sin(a)*r
  • Where Tnet is the Net Torque (N-m)
  • f is the forces (N) 
  • a is the angles (degrees) 
  • r is the radius (m) 

How to Calculate Net Torque?

The following example problems outline how to calculate Net Torque.

Example Problem #1

  1. First, determine the forces (N). In this example, the forces (N) are determined to be 10,30,5 .
  2. Next, determine the angles (degrees). For this problem, the angles (degrees) are measured to be 5,10,75 .
  3. Next, determine the radius (m). In this case, the radius (m) is found to be 4.
  4. Finally, calculate the Net Torque using the formula above: 

Tnet = ∑ f*sin(a)*r

Inserting the values from above and solving yields: 

Tnet = ∑ f*sin(a)*r = 43.64 (N-m)

Example Problem #2

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

forces (N) = 6,8,9

angles (degrees) = 20,30,60

radius (m) = 10

Enter these given values into the calculator or above yields: 

Tnet = 138.463 (N-m)
