Answer D is verignon theorem so C is correct.

Abhilash said: 7 years ago

OPTION D is the correct answer.

Sohan said: 7 years ago

Option D is correct due to Varignon's Theorem.

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 .

Sandip Thakkar said: 6 years ago

Option D is for Varingnon Principle.

Ref RS Khurmi.

Bhavani said: 6 years ago

For equilibrium resultant must be zero, hence C is correct.

What is difference between varignon's theorem and law of moments?

Karthik said: 4 years ago

Varignon or law of moments.

Both are same.

So, Option D is correct.

Abhilash said: 3 years ago

Option D is the correct answer.
