Minor Diameter of External Thread given Pitch and Major Diameter of Internal Thread Solution

STEP 0: Pre-Calculation Summary

Formula Used

Minor Diameter of External Thread = Major Diameter of Internal Thread-(1.227*Pitch of Threads)
d_c = D-(1.227*p)
This formula uses 3 Variables

Variables Used

Minor Diameter of External Thread - (Measured in Meter) - The Minor Diameter of External Thread is the diameter of the imaginary co-axial cylinder that just touches the base of an external thread.
Major Diameter of Internal Thread - (Measured in Meter) - The Major Diameter of Internal Thread is defined as the sum of minor diameter of the internal thread and 1.25 times the value of the height of the fundamental triangle.
Pitch of Threads - (Measured in Meter) - Pitch of Threads is the distance between two adjacent threads on a screw, bolt or nut.

STEP 1: Convert Input(s) to Base Unit

Major Diameter of Internal Thread: 30 Millimeter --> 0.03 Meter (Check conversion here)
Pitch of Threads: 3.99 Millimeter --> 0.00399 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

d_c = D-(1.227*p) --> 0.03-(1.227*0.00399)

Evaluating ... ...

d_c = 0.02510427

STEP 3: Convert Result to Output's Unit

0.02510427 Meter -->25.10427 Millimeter (Check conversion here)

FINAL ANSWER

25.10427 Millimeter <-- Minor Diameter of External Thread

(Calculation completed in 00.004 seconds)
