## Initial Preload Due to Bolt Tightening Solution

STEP 0: Pre-Calculation Summary
Formula Used
Pl = Pb-ΔP
This formula uses 2 Variables
Variables Used
resultant load on the bolt - resultant load on the bolt is the total resultant force/load acting on the bolt after tightening the bolt. (Measured in Newton)
Change In External Load - The Change In External Load Value (Measured in Newton)
STEP 1: Convert Input(s) to Base Unit
resultant load on the bolt: 1 Newton --> 1 Newton No Conversion Required
Change In External Load: 10 Newton --> 10 Newton No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Pl = Pb-ΔP --> 1-10
Evaluating ... ...
Pl = -9
STEP 3: Convert Result to Output's Unit
-9 Newton --> No Conversion Required
-9 Newton <-- Initial Preload Due to Bolt Tightening
