Enter the applied pressure (psi) and the applied area (in^2) into the Calculator. The calculator will evaluate the Extension Force. 

Extension Force Formula

EF = AP * A

Variables:

  • EF is the Extension Force (lbf)
  • AP is the applied pressure (psi)
  • A is the applied area (in^2)

To calculate Extension Force, multiply the applied pressure by the applied area.

How to Calculate Extension Force?

The following steps outline how to calculate the Extension Force.

  1. First, determine the applied pressure (psi). 
  2. Next, determine the applied area (in^2). 
  3. Next, gather the formula from above = EF = AP * A.
  4. Finally, calculate the Extension Force.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

applied pressure (psi) = 40

applied area (in^2) = 20
