Force | [\(N\)] | [\(lb\)] |
Area | [\(m^2\)] | [\(in^2\)] |
Stress | Pascal = [\(Pa\)] = [\(N/m^2\)] | pound per square inch = [\(psi\)] = [\(lb/in^2\)] |
kiloPascal [\(kPa\)] | \(10^3\) [\(Pa\)] |
megaPascal [\(MPa\)] | \(10^6\) [\(Pa\)] |

Supplemental video:
The components of normal and shear stress can be combined into the stress tensor. This is a symmetric matrix representing the state of stress with respect to three directions.
Heads up!
Stress tensor builds on this content later in the course.
