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)
