Limitations of the Dimensional Method |
| Answer» Limitations of dimensionless analysis:\tThis method does not tell us how to determine the proportionality constant value.\tThe method cannot be considered to derive composite relations. Examples s = ut + 1/2 at2\xa0and 2as = v2\xa0– u2.\t\tA formula containing trigonometric function, exponential function, and logarithmic function can not derive from it.\t\tThe method cannot be used to derive the relationship between more than three quantities. | |
