Work/Energy, which is linear force over a distance, and as such has dimensions [M][L2][T−2], and torque, which is rotational force computed by multiplying linear force by the distance from the point of rotation, and as such has dimensions [M][L2][T−2].

In SI, energy is generally given units of Joules, while torque is generally given in units of Newton-meters.

Answer:

Moment of couple and Work are the two physical quantities whose dimensions are same.

Their dimensional formula is [M^{1}L^{2}T^{-2}]

Explanation:

  • Moment of couple = force × perpendicular distance =[M^{1}L^{2} T^{-2}]
  • Work = force × distance =[M^{1}L^{2}T^{-2}]

  Hence,  Moment of couple and Work have the same dimension.

  • Moment of a couple is calculated by multiplying the size of one  force (F) by the perpendicular distance between  two forces.
