Answer:
1.176m
Explanation:
Local ambient pressure(P1) = 100 kPa
Absolute pressure(P2)=260kPa
Net pressure=absolute pressure-local ambient absolute pressure
Net pressure=P1(absolute pressure)-P2(local ambient absolute pressure)
Net pressure=260-100=160kPa
Pressure= ρgh
160kPa=13600*10*h
h=
h=1.176m
Answer:
the correct answer is option A
Explanation:
given,
Load = 6000 lbf
depth = 3.5 ft
distance from the load = 4 ft
vertical stress =
=
= 28.96 lbf/ft²
= 29 lbf/ft²
hence, the correct answer is option A
