Core Diameter of Power Screw Solution

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

FIRST Step Consider the formula

d c = d - p

Next Step Substitute values of Variables

∴

d c = 50mm - 7.8mm

Next Step Convert Units

∴

d c = 0.05m - 0.0078m

Next Step Prepare to Evaluate

∴

d c = 0.05 - 0.0078

Next Step Evaluate

∴

d c = 0.0422m

LAST Step Convert to Output's Unit

∴

d c = 42.2mm
