Initial Preload due to Bolt tightening Solution

STEP 0: Pre-Calculation Summary

Formula Used

Initial Preload Due to Bolt Tightening = Resultant load on pressurized cylinder bolt-Increase in Bolt Load of Cylinder
P_l = P_b-ΔP_i
This formula uses 3 Variables

Variables Used

Initial Preload Due to Bolt Tightening - (Measured in Newton) - Initial preload due to bolt tightening value is the tension created in a fastener when it is tightened.
Resultant load on pressurized cylinder bolt - (Measured in Newton) - Resultant load on pressurized cylinder bolt is the total resultant force/load acting on the bolt after tightening the bolt.
Increase in Bolt Load of Cylinder - (Measured in Newton) - Increase in Bolt Load of Cylinder is the amount of variation in the externally applied force or load by the bolt or on the bolt by the effect of increase in pressure inside the cylinder.

STEP 1: Convert Input(s) to Base Unit

Resultant load on pressurized cylinder bolt: 24500 Newton --> 24500 Newton No Conversion Required
Increase in Bolt Load of Cylinder: 5050 Newton --> 5050 Newton No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_l = P_b-ΔP_i --> 24500-5050

Evaluating ... ...

P_l = 19450

STEP 3: Convert Result to Output's Unit

19450 Newton --> No Conversion Required

FINAL ANSWER

19450 Newton <-- Initial Preload Due to Bolt Tightening
