Breakaway Torque Formula
The following two example problems outline the steps and information needed to calculate the Breakaway Torque.
BT = BF * SL / (2*pi)
Variables:
- BT is the Breakaway Torque (lbf-in)
- BT is the breakaway force (lbf)
- SL is the screw lead (in)
To calculate a breakaway torque, multiply the breakaway force by the screw lead, then divide by 2 times pi.
How to Calculate Breakaway Torque?
The following steps outline how to calculate the Breakaway Torque.
- First, determine the breakaway force (lbf).
- Next, determine the screw lead (in).
- Next, gather the formula from above = BT = BF * SL / (2*pi).
- Finally, calculate the Breakaway Torque.
- 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.
breakaway force (lbf) = 300
screw lead (in) = 5
BT = BF * SL / (2*pi) = ?
