An 18-wheeler is crossing a 4 kilometer bridge that can only support 10,000 kilograms and that's exactly how much the rig weighs. Halfway across the bridge a 30 gram sparrow lands on the cab, but the bridge doesn't collapse. Why not?

Here is a series of numbers. What is the next number in the sequence?

The next number tells you what the number is before it

#1 The truck loses gas while its driving so it will weigh less then when it starts on the bridge.
#2 1113213211

The truck burns fuel so it weighs less and the driver may have have parked it and left before the sparrow landed.

The sparrow pooped at the same time as the driver puked.

It starts with one one and then the next number has two ones. That continues throughout the numbers.

Every three lines it counts up but in between those lines it adds 1\'s and 2\'s until it gets to 3

Q1: If the bridge supports 10,000 kilograms and the the rig weighs 10,000 kilograms then it doesn\'t matter if a 30 gram bird lands on the rig because it weighs grams not kilograms. Q2: The next number in the sequence is 1111222121312

2. The numbers add up to the line number

If the truck was driving for too long the truck would eventually loose gas and gas puts more weight on the truck and bridge so it would way less if it ran out of gas.

the tuck loses gas

#1 the people who tested the bridge were off by 30 kilograms or the driver threw up his lunch over the side of the brigdge the exact moment the bird lands or the 18 wheeler poped a tier and the truck fell off the bridge
#2 i have absolutly NO clue

The vehicle looses gas
Comment Posted on February 22, 2012 at 02:21 PM by SwagMa$ter21

Because while your driving you lose some gas

1. The driver was not inside the truck.
Comment Posted on February 22, 2012 at 02:21 PM by quintonia

It did not collapse because the weight was not over the limit. If it was over the limit it would not have collapsed.

Q1:The rig may weigh less than 1000 pounds and so it will not matter. Or else it just dosen\'t that the sparrowonly wighs 30 grams which means that it dosen\'t add anothe kilagram.
