Strength of Materials According to principle of moments if a system of coplanar forces is in equilibrium, then the algebraic sum of their moments about any point in their plane is zero the algebraic sum of the moments of any two forces about any point is equal to moment of theiwesultant about the same point positive and negative couples can be balanced if a system of coplanar forces is in equilibrium, then their algebraic sum is zero if a system of coplanar forces is in equilibrium, then the algebraic sum of their moments about any point in their plane is zero the algebraic sum of the moments of any two forces about any point is equal to moment of theiwesultant about the same point positive and negative couples can be balanced if a system of coplanar forces is in equilibrium, then their algebraic sum is zero ANSWER DOWNLOAD EXAMIANS APP
