You inspect a submarine a submarine and the customer wants to
know the maximun safe depth it can operate at. The biggest concern
is a 17.2cm diameter window which is 8.6cm thick. The glass can
withstand forces up to 1.1*10^6 N. What is the submarine’s maximum
safe depth? The pressure inside the sub is maintained at 1.0
atm.
What is the maximum depth the sub can go to without worrying
about the window?
A: .0147 m
B: 4690.11 m
C: .0418 m
D: 34.688 m
E: 144397.12 m
F: none of the above
EQUATIONS WOULD BE APPRECIATED SO I CAN TRY AND UNDERSTAND
IT.
