Nominal Diameter of Power Screw Solution

Follow our step by step solution on how to calculate Nominal Diameter of Power Screw?

FIRST Step Consider the formula

d = d c + p

Next Step Substitute values of Variables

∴

d = 42mm + 7.8mm

Next Step Convert Units

∴

d = 0.042m + 0.0078m

Next Step Prepare to Evaluate

∴

d = 0.042 + 0.0078

Next Step Evaluate

∴

d = 0.0498m

LAST Step Convert to Output's Unit

∴

d = 49.8mm
