Step 2:: Understanding Stress
Stress is defined as force per unit area, which means the units will depend on the units of force and area in each measurement system.
Step 3:: U.
- Therefore, stress units are: $$\frac{\text{pounds}}{\text{square inch}} = \text{psi (pounds per square inch)}
S. Customary Units In the U. S. customary system: - Force is measured in pounds (lb) - Area is measured in square inches (in²)
Step 4:: SI (Metric) System
- Therefore, stress units are: $$\frac{\text{newtons}}{\text{square meter}} = \text{N/m}^{2} = \text{pascal (Pa)}
In the SI system: - Force is measured in newtons (N) - Area is measured in square meters (m²)
Final Answer
- U. S. Customary Units: psi (pounds per square inch) - SI Units: Pa (pascal, N/m²)
