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

Follow our step by step solution on how to calculate Minor Diameter of External Thread given Pitch and Major Diameter of Internal Thread?

FIRST Step Consider the formula

d c = D - (1.227 \cdot p)

Next Step Substitute values of Variables

∴

d c = 30mm - (1.227 \cdot 3.99mm)

Next Step Convert Units

∴

d c = 0.03m - (1.227 \cdot 0.004m)

Next Step Prepare to Evaluate

∴

d c = 0.03 - (1.227 \cdot 0.004)

Next Step Evaluate

∴

d c = 0.02510427m

Next Step Convert to Output's Unit

∴

d c = 25.10427mm

LAST Step Rounding Answer

∴

d c = 25.1043mm
