Question

The principle of submerged mass density method is_______

(a) Equilibrium of floating bodies

(b) Stroke’s law

(c) Archimedes’ principle

(d) Darcy’s law

I have been asked this question during an interview.

My question is taken from Determination of in-situ Density topic in section Index Properties Determination of Geotechnical Engineering I

Answer 1

Correct answer is (c) Archimedes’ principle

To explain: The submerged mass density is based on Archimedes’ principle that when a body is submerged in water, the reduction in its mass is equal to the mass of volume of water displaced.
