Enter the stress area, tensile strength, and safety factor into the calculator to determine the thread pull out force. This calculator helps in assessing the force required to pull a threaded connection out of its engagement.
Thread Pull Out Force Formula
The following formula is used to calculate the thread pull out force:
F = (A * S) / SF
Variables:
- F is the pull out force (pounds)
- A is the stress area (square inches)
- S is the tensile strength (psi)
- SF is the safety factor
To calculate the thread pull out force, multiply the stress area by the tensile strength and then divide by the safety factor.
What is Thread Pull Out Force?
Thread pull out force is the force required to pull a threaded connection out of its engagement. It is a critical value in engineering design, particularly in applications where mechanical fasteners are used. The pull out force depends on the material properties, the geometry of the threads, and the safety factor applied to ensure the connection remains secure under expected loads.
How to Calculate Thread Pull Out Force?
The following steps outline how to calculate the Thread Pull Out Force.
- First, determine the stress area (A) in square inches.
- Next, determine the tensile strength (S) in psi.
- Next, determine the safety factor (SF).
- Next, gather the formula from above = F = (A * S) / SF.
- Finally, calculate the Thread Pull Out Force (F) in pounds.
- 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.
stress area (A) = 0.5 square inches
tensile strength (S) = 60,000 psi
safety factor (SF) = 1.5
