Describe THREE fundamental quantities and THREE practical uses of dimensional analysis in engineering.

Here are the solutions to the problems.

14. a) Describe THREE fundamental quantities that would be useful in the relation.
The three fundamental quantities commonly used in dimensional analysis are:

• Mass (M)
• Length (L)
• Time (T)

14. b) Elaborate THREE practical uses of dimensional analysis in engineering.
Three practical uses of dimensional analysis in engineering are:

• Checking dimensional homogeneity: It ensures that all terms in an equation have consistent units, which helps in identifying errors in formulas.
• Deriving relationships between physical quantities: It can be used to determine the form of an equation relating several variables, especially when the exact relationship is unknown.
• *Scaling and
