The question is this. "Is it possible for an object to be in a state of equilibrium when forces of 10N, 20N and 40N act upon it?" I'm thinking yes, because you can always have the 10 N and 20 N force acting in the same direction and the 40N acting on both at a slight angle, equalling 30. But I don't know if I'm right. This seems like a really simple question, yet I don't know how to answer it. Any help would be greatly appreciated.
