A truck driver approaches a bridge that has a weight limit of 5000 kilograms. He and his truck weigh 4950 kilograms so he would be able to cross it were it not for his 100-kilogram cargo 鈥� a flock of pigeons loose in the back of the truck. He has the bright idea of banging on the side of the truck to scare all the birds into taking flight and then he quickly drives across the bridge. Does it work?
