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

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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.
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.
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

Minor Diameter of External Thread: 24.89 Millimeter --> 0.02489 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 = d_c+(1.227*p) --> 0.02489+(1.227*0.00399)

Evaluating ... ...

D = 0.02978573

STEP 3: Convert Result to Output's Unit

0.02978573 Meter -->29.78573 Millimeter (Check conversion here)

FINAL ANSWER

29.78573 Millimeter <-- Major Diameter of Internal Thread

(Calculation completed in 00.020 seconds)
