Riddle:

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? Give a reason.

No it does not collapse. Because it has driven a half mile - you would subtract the gas used from the total weight of the truck
