Interesting Logical Puzzle
This one's an interesting puzzle and DOES NOT involve any MECHANICS!
There's a Bridge 2.4 km long with a load handling capacity of exactly 1 tonne and is bound to collapse if load increases by even a single gram than a tonne.
A bus, loaded fully with passengers, of weight exactly a tonne is crossing over the bridge. At exactly 3/4th of the length of the bridge a Crow comes (out of the Blue) and sits on top of the Bus.
But to everyone's surprise, the Bridge doesn't collapse and the bus crosses it safely.
Why?

As the bus crosses the bridge ………..so some part of the fuel is also consumed to travel 3/4th length of the bridge……. so the fuel consumed is exactly balanced by the weight of the crow….so the bridge will not collapse……

when we are speaking about the capacity and a 1ton capacity means it can handle one ton per meter so the bus is only 1 ton over 2 klm and its waight if spreaded then it wont equall even .5 kg over each meter

The Bus loses the weight of the Oil (Diesel) consumed and its comparable to the weight of the bird!

at about 75%(3/4) the lenght of the bridge the bus has lost enough fuel to make total weight less than 1 ton,so nothing happens

the luggages from the bus was thrown out so that they could escape

Another Answer:
Load handling capacity means the maximum weight that can be held at all points on the bridge. Thus, at 3/4ths the length of the bridge, it would typically be higher than at it’s weakest point, which is again, typically, the center.

All the passengers scream at the thought of their death and the air leaving their lungs makes them lighter.

By the time the Bus traveled 3/4th distance the fuel consumed is more than the wieght of the bird.
July 30th, 2010 - 23:20
By the time the Bus travel 3/4 distance the fuel must have been consumed which is more than the wieght of the bird. That is the reason the bus passed through the bridge.

@man: FYI the length of the given bridge is 2.4 km and not 2.4 meters. Guys try. The answer is really interesting
July 30th, 2010 - 18:03
because the bus lenghth is greater than 1.8 mts.
