Pressure From Torque Formula

The following formula is used to calculate the Pressure From Torque.

P = T/r/A
  • Where P is the Pressure From Torque (Pa)
  • T is the torque (N-m) 
  • r is the radius (m) 
  • A is the area (m^2) 

To calculate pressure from torque, divide the torque by the radius, then again by the area.

How to Calculate Pressure From Torque?

The following example problems outline how to calculate the Pressure From Torque.

Example Problem #1

  1. First, determine the torque (N-m). In this example, the torque (N-m) is given as 500 .
  2. Next, determine the radius (m). For this problem, the radius (m) is given as  3 .
  3. Next, determine the area (m^2). In this case, the area (m^2) is found to be 5.
  4. Finally, calculate the Pressure From Torque using the formula above: 

P = T/r/A

Inserting the values from above and solving yields: 

P =500/3/5 = 33.33 (Pa)

Example Problem #2

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

torque (N-m) = 600

radius (m) = 7

area (m^2) = 8

Enter these given values yields: 

P = 600/7/8 = 10.71 (Pa)
