The couple is simplified easily with the help of right hand rule. But the forces simplification is not possible as there is no such system of rules so that the forces can be simplified.

A. The first part of the statement is false and another part is true

B. The first part of the statement is false and another part is false too

C. The first part of the statement is true and another part is false

D. The first part of the statement is true and another part is true too

This question was addressed to me by my school principal while I was bunking the class.

This is a very interesting question from Simplification of a Force and Couple System in division Force System Resultants of Engineering Mechanics

The correct choice is C. The first part of the statement is true and another part is false

The explanation is: Both of them are vector quantities. And both of them can be easily simplified. If taken in the vector form then the task is even easier. Thus it is not necessary for the force or the couple to be vector only, even if the magnitude is taken, the simplification is done in the 2D. Forces are simplified on the basis of the algebra.
