Question
Any two coplanar couples of equal moments
- Balance each other
- Are equivalent
- Need not be equivalent
- None of these
Hint:
In this question, given is any two coplanar couples of equal moments. If a body is submitted to two or more coplanar couples, then the resultant force acting on it is zero.
The correct answer is: Are equivalent
It is a fundamental concept.
Here we have to find the which option is correct when any two coplanar couples of equal moments
Firstly, we have two coplanar couples, then the resultant acting force is zero.
Moments of couple is called torque.
A couple consists of two forces acting opposite to each but not at the same point, so as to produce a torque which makes the object rotate. The net force applied by a couple is zero as the forces are equal and opposite.
When two couples are present whose moments are equal and opposite then the forces are already balanced.
Therefore, the correct answer is Balance each other.
In this question, two coplanar couples of equal moments. Moments of couple is called torque. When two couples are present whose moments are equal and opposite then the forces are already balanced.
