Question

an air filled balloon is at a depth of 1km below the water level in an ocean. determine the normal stress on the balloon

Answer 1

Explanation:

The stress an object can bear according to its area is called normal stress. We have a balloon at a depth of 1 km below the water level in an ocean. We have to determine the normal stress balloon has if the atmospheric pressure is 10^5. The answer of normal stress is 9.9x10^6 per unit area.

Answer 2

Explanation:

1. formula atmospheric pressure + hpg
2. ap=10^5
3. h=1000
4. 1 km =1000
5. g=9.8
6. ....
7. ...
8. ....
9. 10^5+1000×1000×9.8
