Question

Mention the limitations of method of Dimensional analysis .​

Answer 1

Answer:

Limitations of dimensional method. Although dimensional analysis is very useful, it cannot lead us too far because of the following reasons: Dimensional method cannot be used to derive equations involving addition and substraction. Numerical constants having no dimensions cannot be obtained by method of dimensions.

Limitations of Dimensional analysis are:-

1) The method does not give any information about dimension less quantity K.

2)It fails when a physical quantity depends on more than three physical quantity.

3)It fails when a physical quantity is the sum or difference of two or more quantities.

$ex = > s = ut + \frac{1}{2} a {t}^{2}$

4) It also fails to derive the relationship which involves trignometric , logarithmic or exponential functions.

5) It is difficult to identify the factors on which the physical quantity depends. The method becomes more complicated when dimensional constant like G, h is envolved.
