Question

Two opposite forces acting perpendicular to an axis cause

Answer 1

Two opposite forces which are acting perpendicular to an axis cause the moment of couple or torque.

What is couple?

Couple is the pair of force of equal magnitude which acts in opposite direction to each other. The moment of couple is known as the troque, which can be calculate as,

$\tau=Fs$

Here, (F) is the magnitude of one of the force and (s) is the perpendicular distance of force acting on axis.

Here, the two opposite forces are given which acts perpendicular to an axis. Now suppose there is the magnitude of both the force (F) is equal and the perpendicular distance from the axis is also same.

Thus, from the above definition of moment of couple, they produce, torque or moment of couple.

Hence, the two opposite forces which are acting perpendicular to an axis cause the moment of couple or torque.
