This formula uses 1 Constants, 5 Variables
Constants Used
pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288
Variables Used
Core diameter of screw - (Measured in Meter) - Core diameter of screw is defined as the smallest diameter of the thread of the screw or nut. The term “minor diameter” replaces the term “core diameter” as applied to the thread of a screw.
Axial load on screw - (Measured in Newton) - Axial load on screw is the instantaneous load applied to the screw along its axis.
Transverse Shear Stress in Screw - (Measured in Pascal) - Transverse Shear Stress in Screw is the resistance force developed per unit cross-sectional area by the screw to avoid transverse deformation.
Thread Thickness - (Measured in Meter) - Thread Thickness is defined as the thickness of a single thread.
Number of Engaged Threads - A number of Engaged Threads of a screw/bolt are the count of threads of the screw/bolt that are currently in engagement with the nut.
STEP 1: Convert Input(s) to Base Unit
Axial load on screw: 131000 Newton --> 131000 Newton No Conversion Required
Transverse Shear Stress in Screw: 27.6 Newton per Square Millimeter --> 27600000 Pascal (Check conversion ​here)
Thread Thickness: 4 Millimeter --> 0.004 Meter (Check conversion ​here)
Number of Engaged Threads: 9 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
dc = Wa/(τs*pi*t*z) --> 131000/(27600000*pi*0.004*9)
Evaluating ... ...
dc = 0.0419671850745537
STEP 3: Convert Result to Output's Unit
0.0419671850745537 Meter -->41.9671850745537 Millimeter (Check conversion ​here)
FINAL ANSWER
41.9671850745537 41.96719 Millimeter <-- Core diameter of screw
(Calculation completed in 00.004 seconds)

Mean Diameter of Power Screw
​ Go Mean Diameter of Power Screw = Nominal diameter of screw-0.5*Pitch of power screw thread
Nominal Diameter of Power Screw
​ Go Nominal diameter of screw = Core diameter of screw+Pitch of power screw thread
Core Diameter of Power Screw
​ Go Core diameter of screw = Nominal diameter of screw-Pitch of power screw thread
Pitch of Power Screw
​ Go Pitch of power screw thread = Nominal diameter of screw-Core diameter of screw
