Engineering Mechanics According to the law of moments, if a number of coplanar forces acting on a particle are in equilibrium, then Their algebraic sum is zero The algebraic sum of their moments about any point in their plane is zero Their lines of action are at equal distances The algebraic sum of their moments about any point is equal to the moment of their resultant force about the same point Their algebraic sum is zero The algebraic sum of their moments about any point in their plane is zero Their lines of action are at equal distances The algebraic sum of their moments about any point is equal to the moment of their resultant force about the same point ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics The forces, which meet at one point, but their lines of action do not lie in a plane, are called Non-coplanar concurrent forces Non-coplanar non-concurrent forces Intersecting forces Coplanar non-concurrent forces Non-coplanar concurrent forces Non-coplanar non-concurrent forces Intersecting forces Coplanar non-concurrent forces ANSWER DOWNLOAD EXAMIANS APP
