According to principle of moments________?
Apositive and negative couples can be balanced
Bif a system of coplanar forces is in equilibrium, then their algebraic sum is zero
Cthe algebraic sum of the moments of any two forces about any point is equal to moment of theiwesultant about the same point
Dnone of the above
Eif a system of coplanar forces is in equilibrium, then the algebraic sum of their moments about any point in their plane is zero
Correct answer
E. if a system of coplanar forces is in equilibrium, then the algebraic sum of their moments about any point in their plane is zero
Explanation
The correct answer is if a system of coplanar forces is in equilibrium, then the algebraic sum of their moments about any point in their plane is zero.
