Varignon or law of moments.

Both are same.

So, Option D is correct.

What is difference between varignon's theorem and law of moments?
Bhavani said:   6 years ago
For equilibrium resultant must be zero, hence C is correct.

Option D is for Varingnon Principle.

Ref RS Khurmi.
Vaishnavi karad said:   6 years ago
Option C is correct.

An algebraic sum equal to the moment of resultant means zero.

Ref: RS Khurmi and JK Gupta .
