Question

Mention any two limitations of dimensional analysis.

Answer 1

1. Dimensional analysis is defined as the method of getting the relation among the physical quantities by identifying their dimensions and the dimension of any physical quantity is the relation of the fundamental physical quantities such as mass, length and time.
2. But dimensional analysis has some limitations out of which two are given below-

1. This method is unable to determine the value of the proportionality constant.
2. This method is unable to derive the formula containing trigonometric function, exponential function, and logarithmic function.
