Truck on Bridge

A large truck is crossing a bridge 1 mile long. The bridge can only hold 14000 lbs, which is the exact weight of the truck. The truck makes it half way across the bridge and stops. A bird lands on the truck. Does the bridge collapse?


No, it will not collapse. The truck has been driven for half a mile so the weight of the used fuel has to be subtracted from the total weight of the truck.
