Explanation:
HEYA MATE HERE IS UR ANSWER ❤
In mechanics, a couple refers to two parallel forces that are equal in magnitude, opposite in sense and do not share a line of action. A better term is force couple or pure moment. Its effect is to create rotation without translation, or more generally without any acceleration of the centre of mass.
eg-the forces that two hands apply to turn a steering wheel are often (or should be) a couple. Each hand grips the wheel at points on opposite sides of the shaft. When they apply a force that is equal in magnitude yet opposite in direction the wheel rotates.

Answer:
two equal and opposite parallel forces not acting along the same line form a couple . A couple is always needed to produce the rotation. For example: turning steering wheel.
