Stress

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Stress ( $$\sigma$$ ) or ( $$S$$ ) is the force per unit area of cross-section.

formula

$$\sigma = \frac{F}{A}$$

Where:

$$\sigma$$ (Greek symbol sigma) = stress

$$F$$ = force

$$A$$ = area

Solve for:

$$F = \sigma A$$

$$A = \frac{F}{\sigma}\;$$
