What this calculator does

Hooke's Law – Young's Modulus Calculator: Applies the standard mechanics-of-materials relationship for this load case so a student can see how the stress, strain or deflection follows from the geometry and the load.

What your result means

The headline figure tells you how hard the material is being worked, or how much it moves, under the load you entered. Compare it with the allowable value for your material and required factor of safety.

Formula and working

E = stress / strain = (F/A) / (ΔL/L)

  1. 1

    Collect the inputs

    Applied force = 5,000 N; Cross-section area = 100 mm²; Original length = 500 mm; Elongation = 0.5 mm

  2. 2

    Apply the formula

    E = stress / strain = (F/A) / (ΔL/L)

  3. 3

    Result

    Young's modulus = 50,000 MPa

  • This is an educational estimate for learning and checking, not a design deliverable.
  • Real design must follow the governing code or standard for your jurisdiction and be reviewed and signed off by a qualified engineer.
  • Safety factors, load combinations and material certification are the responsibility of the designer, not of this page.

Important limitation

This is an educational estimate based only on the values and formula shown. Verify current rates, rules, units, and professional standards before relying on the result. It is not personalized financial or investment advice.
