The amount of force applied per unit of force of area of material. Nm^-2 |
|
|
|
Strain |
The amount of extension per unit length of material. No units or as a percentage; it’s a ratio. |
Extension |

How do you calculate stress? (σ) |
Force / Cross sectional area |
|
|
|
How do you calculate strain? ε |
Change in length (extension) / Original length (Δx / x) |
Δ |
|
|
How to calculate Young’s Modulus? |
Stress / Strain (E = σ / ε) or Force x Length/extension x Area (E = FL / eA) |
