10.7 A vertical off-shore structure is built to withstand a maximum stress of 109 Pa. Is the structure suitable for putting up on top of an oil well in the ocean? Take the depth of the ocean to be roughly 3 km, and ignore ocean currents.

The maximum allowable stress for the structure, P = Pa
Depth of the ocean, d = 3 km = 3 m
Density of water = kg/
Acceleration due to gravity, g = 9.8 m/s
The pressure exerted because of sea water at the depth d = = 3 Pa
= 2.94 Pa
The maximum allowable stress is more than the pressure, hence the structure is suitable.
