Dimension of stress n strain?? |
| Answer» The SI unit of stress is Newton per square meter. Or we can express the same in terms of Pascal.1 Pascal = 1 Pa = 1 N.m-2.While there is no unit for strain. It is a dimensionless quantity. This is because it is the ratio of change of length to the original length, and therefore it is unitless. | |
