Calculating your young's modulus is straightforward once you know the Young's Modulus formula and what each input means. This guide explains the method in plain language, walks through a manual calculation, and gives worked examples you can follow — then you can do it instantly with the Young's Modulus Calculator.
What is Young's Modulus?
The Young's Modulus calculation tells you your young's modulus from a few simple inputs. The figure you are solving for here is the young's modulus.
The Young's Modulus formula
The core formula is:
Young's modulus = Stress ÷ StrainHere is what each input means:
- Stress — a value measured in Pa. Example: 200,000,000 Pa.
- Strain — a number. Example: 0.001.
How to calculate it step by step
- Write down the stress (for example, 200,000,000 Pa).
- Write down the strain (for example, 0.001).
- Apply the formula above to get your young's modulus.
- Double-check the result with the Young's Modulus Calculator.
Worked examples
Example 1
| Input / Output | Value |
|---|---|
| Stress | 200,000,000 Pa |
| Strain | 0.001 |
| Young's modulus | 200,000,000,000 |
With stress of 200,000,000 Pa and strain of 0.001, the young's modulus works out to 200,000,000,000.
Example 2
With stress of 400,000,000 Pa and strain of 0.001, the young's modulus works out to 400,000,000,000.
| Result | Value |
|---|---|
| Young's modulus | 400,000,000,000 |
Example 3
With stress of 100,000,000 Pa and strain of 0.001, the young's modulus works out to 100,000,000,000.
| Result | Value |
|---|---|
| Young's modulus | 100,000,000,000 |
Tips for an accurate result
- Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
- Round only at the very end. Rounding inputs early can shift the final answer noticeably.
- Re-run the numbers whenever an input changes, rather than estimating from an old result.
