Question

If force, area and density are taken as the fundamental units, the representation of Young's modulus 'Y' will be

Answer 1

Fundamental units are a set of unrelated units of measurement. Young’s modulus is the elastic modulus we use for deformation which takes place when a force which is parallel to the axis of the object is applied to one face while the opposite face is held fixed by another equal force. 


Y = stress / strain 

= force / area x strain
