Question

what is the unit of couple?

Answer 1

Your answer is...
Unit of couple is torque...

Answer 2

Answer: The unit for the torque of the couple is newton meter.

Explanation:

Torque: It is the turning effect of the force.

The expression for the torque is as follows;

$\tau =Frsin\Theta$

Here, F is the force, r is the perpendicular distance and $\Theta$ is the angle between the force and the perpendicular distance.

The SI unit of the torque is N-m.

Couple is formed when two forces which are parallel and unlike but having same magnitude. It does not act along the same line. These forces are acting in an opposite direction.

The unit of torque and couple is newton meter.

Therefore, the correct answer is newton meter.
