Question

If force f, area a and density d are taken as the fundamental quantities, then mass can be represented as

Answer 1

Force = F = mass * acceleration = M L T⁻²

Area = A = meter² = L²

Density = D = mass / volume = M L⁻³

Y = stress / strain = ( Force / Area ) / ( elongation / length)

  = (F / A ) / ( L / L)

  = F A⁻¹
