Diameter of Hole Inside Bolt Solution

STEP 0: Pre-Calculation Summary

Formula Used

Diameter of Hole Inside Bolt = sqrt(Nominal Bolt Diameter^2-Core Diameter of Bolt^2)
d₁ = sqrt(d^2-d_c^2)
This formula uses 1 Functions, 3 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Diameter of Hole Inside Bolt - (Measured in Meter) - The Diameter of Hole inside Bolt is defined as the internal diameter of the hole that is made inside a bolt along its axis for weight reduction.
Nominal Bolt Diameter - (Measured in Meter) - Nominal Bolt Diameter is the diameter equal to the external diameter of the threads or the overall diameter of the part of the bolt.
Core Diameter of Bolt - (Measured in Meter) - Core Diameter of Bolt is defined as the smallest diameter of the thread of the bolt. The term “minor diameter” replaces the term “core diameter” as applied to the thread.

STEP 1: Convert Input(s) to Base Unit

Nominal Bolt Diameter: 15 Millimeter --> 0.015 Meter (Check conversion here)
Core Diameter of Bolt: 12 Millimeter --> 0.012 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

d₁ = sqrt(d^2-d_c^2) --> sqrt(0.015^2-0.012^2)
