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.
suppose the truck runs on solar power then theoretically it would collapse. However it is highly unlikely to happen in real life since the tolerance of objects has a range like 13900lbs - 14100lbs depending on workmanship wear&tear etc.
