A 5-ft diameter 300-lb circular hatch is located on a submarine,
as shown. The submarine is in sea water with a specific weight of
64 lb/ft3 . Determine the following: (a) the resultant force on the
hatch due to the water pressure (b) the location of the resultant
force (distance below the water surface). (c) the magnitude of the
force, F, which should be applied to open the hatch when it is
submerged as shown. It is hinged at the...
