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...

Consider the free-body diagram of a person holding a ball with their arm extended horizontally, as shown below on the left. The ball weighs WB 30 N, and is held at a distance d0.35 m from the elbow (E). The lower arm weighs WA 10N, with the center of mass distance 1- 0.15 m away from E. The biceps muscle applies a vertical upward force B to the lower arm at distance s - 0.03 m from E. a) What...
