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.

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.

T = f.d.

Then T = ma.d.

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

How a=L/T2?

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.

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.

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.

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.

NITSH KUMAR said:   1 decade ago
Force*distance between the force = Work.

Debjyoti Bandyopadhyay said:   1 decade ago
Couple = Force*distance between the force = Work.

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