Calculation Formula

Stretch = (Pounds * Bolt Length) / (E * A)

Where:
Stretch = Linear deformation (inches)
Pounds = Applied force (pounds)
Bolt Length = Gauge length of bolt (inches)
E = Modulus of elasticity of bolt material (typically 30,000,000 psi for steel)
A = Cross-sectional area of bolt (inches²)

Result

0.0000 inches

Working Principle

This calculator uses the formula for linear deformation of a bolt under tension. The stretch (or elongation) of a bolt can be calculated using Hooke's Law:

Stretch = (Pounds * Bolt Length) / (E * A)

Where:

  • Pounds is the applied force in pounds.
  • Bolt Length is the gauge length of the bolt in inches.
  • E is the modulus of elasticity of the bolt material (typically 30,000,000 psi for steel).
  • A is the cross-sectional area of the bolt in square inches.

This calculation is useful in mechanical engineering for determining how much a bolt will stretch under a given load, which is important for ensuring proper clamping force and preventing bolt failure.
