Major Diameter of External Thread given Height of Fundamental Triangle Solution

STEP 0: Pre-Calculation Summary

Formula Used

Major Diameter of External Thread = Pitch Diameter of External Thread+(0.75*Height of Fundamental Triangle)
d = d_p+(0.75*H)
This formula uses 3 Variables

Variables Used

Major Diameter of External Thread - (Measured in Meter) - Major Diameter of External Thread is the diameter of the imaginary co-axial cylinder that just touches the crest of an external thread.
Pitch Diameter of External Thread - (Measured in Meter) - Pitch Diameter of External Thread is the simple effective diameter of external screw thread, approximately halfway between the major and minor diameters.
Height of Fundamental Triangle - (Measured in Meter) - Height of Fundamental Triangle is the height of the thread when the profile is extended to a sharp vee form.

STEP 1: Convert Input(s) to Base Unit

Pitch Diameter of External Thread: 27.2 Millimeter --> 0.0272 Meter (Check conversion here)
Height of Fundamental Triangle: 3.46 Millimeter --> 0.00346 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

d = d_p+(0.75*H) --> 0.0272+(0.75*0.00346)

Evaluating ... ...

d = 0.029795

STEP 3: Convert Result to Output's Unit

0.029795 Meter -->29.795 Millimeter (Check conversion here)

FINAL ANSWER

29.795 Millimeter <-- Major Diameter of External Thread

(Calculation completed in 00.020 seconds)
