1am playing tug-o-war with my three nephews. The youngest in pulling with a force of 189 N. The middle child is pulling with a force of 334 N. The oldest is pulling with a force of 657 N. I am on a team with the youngest child. If I want to keep the four of us in equilibrium, how hard (in newtons) must I pull?
