Question

Write down three limitations and three applications of methods of dimension​

Answer 1

Answer:

The method cannot be considered to derive composite relations. Examples s = ut + 1/2 at2 and 2as = v2 – u2. A formula containing trigonometric function, exponential function, and logarithmic function can not derive from it. The method cannot be used to derive the relationship between more than three quantities.

We make use of dimensional analysis for three prominent reasons: To check the consistency of a dimensional equation. To derive the relation between physical quantities in physical phenomena. To change units from one system to another.
