The shelves in my refrigerator are metal lattices that are held up by being slipped into two small (about 1 inch long) hollow boxes or "pockets" attached to the interior back wall of the refrigerator. If I put a full gallon of milk on the shelf, is it more likely to break the pocket if I place it near to the back of the refrigerator or near to the front? Explain your answer in terms of the physics we have learned. If the milk is the only thing on the shelf, estimate the downward force that the shelf exerts on the front of the pocket when the milk is placed at the front of the shelf.
