Question

example of couple in physics

Answer 1

the forces that two hands apply to turn a steering wheel are often (or should be) a couple.

Answer 2

A couple consists of two parallel forces that are equal in magnitude, opposite in sense and do not share a line of action . BUT, the resultant of a couple is not zero; it is a pure moment. For example, the forces that two hands apply to turn a steering wheel are often (or should be) a couple.
