Height of Fundamental Triangle of Screw Threads given Pitch Diameter of Internal Thread Solution

STEP 0: Pre-Calculation Summary

Formula Used

Height of Fundamental Triangle = (Major Diameter of Internal Thread-Pitch Diameter of Internal Thread)/0.75
H = (D-D_p)/0.75
This formula uses 3 Variables

Variables Used

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.
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 Diameter of Internal Thread - (Measured in Meter) - The Pitch Diameter of Internal Thread is the simple effective diameter of external screw thread, approximately halfway between the major and minor diameters.

STEP 1: Convert Input(s) to Base Unit

Major Diameter of Internal Thread: 30 Millimeter --> 0.03 Meter (Check conversion here)
Pitch Diameter of Internal Thread: 27.4 Millimeter --> 0.0274 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

H = (D-D_p)/0.75 --> (0.03-0.0274)/0.75

Evaluating ... ...

H = 0.00346666666666666

STEP 3: Convert Result to Output's Unit

0.00346666666666666 Meter -->3.46666666666666 Millimeter (Check conversion here)

FINAL ANSWER

3.46666666666666 ≈ 3.466667 Millimeter <-- Height of Fundamental Triangle

(Calculation completed in 00.004 seconds)
