Beyond limits of material strength, this can lead to a permanent shape change or structural failure. The dimension of stress is the same as that of pressure, and therefore the SI unit for stress is the pascal (Pa), which is equivalent to one newton per square meter (N/m²). In Imperial units, stress can be measured in pound-force per square inch, which is abbreviated as psi. Using the Pressure ...
