A cubical box is filled with sand and weighs 648 N. As in the figure, a horizontal force F is applied at one of the upper edges in order to tip the box (start it to tip over). What is the minimum force required? [Hint: this is an equilibrium problem where we want to find the greatest applied force F such that the torques will still add to zero. Second hint: when the box is on the verge of tipping, where will the normal force be applied?]. Note that there is friction between the box and the surface it rests on.
