Question
What are the limitations of dimensional analysis?
Solution
The limitations of dimensional analysis are:
(i) We cannot derive the formulae involving trigonometric functions, exponential functions, log functions etc., which have no dimension.
(ii) It does not give us any information about the dimensional constants in the formula.
(iv) We cannot find the exact sign of plus or minus connecting two or more terms in relation.
(v) This method fails to derive the relation of mechanics involving more than three physical quantities.
