COUPLES

 

A  couple (in Physics) is a system of two opposite ,parallel and equal forces not acting along the same line.

 

In fig 1 above

                          F1=F2

The turning moment of a couple is the product of one of the forces and the distance of line of action between the two forces.

Example of couple is seen in turning of a water tap  T valve  ON or OFF. Equal but opposite force is applied to either side of the tap valve.
