Frictional Torque Formula
The following formula is used to calculate the Frictional Torque.
Tf = N*u*r
- Where Tf is the Frictional Torque (N-m)
- N is the normal force (N)
- u is the coefficient of friction
- r is the radius (m)
How to Calculate Frictional Torque?
The following example problems outline how to calculate the Frictional Torque.
Example Problem #1
- First, determine the normal force (N). In this example, the normal force (N) is given as 5 .
- Next, determine the coefficient of friction. For this problem, the coefficient of friction is given as 10 .
- Next, determine the radius (m). In this case, the radius (m) is found to be 20.
- Finally, calculate the Frictional Torque using the formula above:
Tf = N*u*r
Inserting the values from above and solving yields:
Tf = 5*10*20 = 1000 (N-m)
Example Problem #2
Using the same method as above, determine the variables required by the equation. For this example problem, these are provided as:
normal force (N) = 10
coefficient of friction = 20
radius (m) = 30
Enter these given values yields:
Tf = 10*20*30 = 6000 (N-m)
