Formula for Couple acting on body (T)=F*d
=Ma*d [F=M*a]
=M*dv/t*d [a==(vf-vi)/t)]
=M*(d/t/t)*d
=Md^2/t^2
=ML^2T^-2

Two equal and opposite parallel forces acting along different lines on a body constitute a couple.

The product of force and perpendicular distance between two force.

So force*distance = couple of force.

UNIT: NEWTON*METER = MLT^-2 L = ML^2T^-2.

T = f.d.

Then T = ma.d.

= M.L/T2.L (a=L/T2) & (d=L).
= ML2/T2.

= ML2T-2.Formula for Couple acting on body (T)=F*d.
= Ma*d [F=M*a].

= M*dv/t*d [a==(vf-vi)/t)].
= M*(d/t/t)*d.

= Md^2/t^2.
= ML^2T^-2.

Work and couple are two different things work helps us to move an object moment or couple indicates the possibilities for the work to be done.

COUPLE ACTING ON BODY MEANS TORQUE. SO USING THE FORMULA:

T = f.d.
THEN T= ma.d.

= M.L/T2.L (a=L/T2) & (d=L).
= ML2/T2.
= ML2T-2.

t=f.d f=ma m=M and d=L.

= M(a=v/t).L where v= s/t s=L
=M(L/t2).L WHERE t2 go square
=ML2T-2.

Couple acting on body, unit is N-mm.
N = kg.mm.s^-2.
N-mm = kg.mm^2.s^-2.
N-mm = ML^2T^-2.

Force =m*a
and couple= force*distance
units of force =m*l*t^-2
and couple= ml^2t^-2.

Couple = Force*distance between the force = Work.

Dimension of Work is ML^2T^-2.

T = f.d.

Then T = ma.d.

= M.L/T2.L (a=L/T2) & (d=L).
= ML2/T2.
