Stress=ForceArea=Nm2 2. Strain is a dimensionless quantity (it is the ratio of change in length to original length), so it has no units. 3. Therefore, Young's modulus can be expressed as: Y=StressStrain=N/m21=N/m2 4. In MKS units, 1 N/m² is also known as 1 Pascal (Pa)...
The dimensions ofdynamic viscosityareforce× time ÷ area. The unit of viscosity, accordingly, isnewton-second per squaremetre, which is usually expressed aspascal-second inSIunits.
