Variables Used

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 nut - (Measured in Pascal) - Transverse shear stress in nut is the resistance force developed per unit cross-sectional area by the nut to avoid transverse deformation.
Thread Thickness - (Measured in Meter) - Thread Thickness is defined as the thickness of a single thread.
Nominal diameter of screw - (Measured in Meter) - Nominal diameter of screw is defined as the diameter of the cylinder touching the external threads of the screw.
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

Transverse shear stress in nut: 23.3 Newton per Square Millimeter --> 23300000 Pascal (Check conversion here)
Thread Thickness: 4 Millimeter --> 0.004 Meter (Check conversion here)
Nominal diameter of screw: 50 Millimeter --> 0.05 Meter (Check conversion here)
Number of Engaged Threads: 9 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

W_a = pi*t_n*t*d*z --> pi*23300000*0.004*0.05*9

Evaluating ... ...

W_a = 131758.395891556

STEP 3: Convert Result to Output's Unit

131758.395891556 Newton --> No Conversion Required

FINAL ANSWER

131758.395891556 ≈ 131758.4 Newton <-- Axial load on screw

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

Axial Load on Screw given Transverse Shear Stress at Root of Nut Formula

Axial load on screw = pi*Transverse shear stress in nut*Thread Thickness*Nominal diameter of screw*Number of Engaged Threads
W_a = pi*t_n*t*d*z

Optimum Axial Load

Optimum Axial Load is usually taken as half of the calculated load, so as maintain a Factor of Safety in case of unwanted occurrences such as jerking, over-tightening.
