An undersea camera (Figure 5.36 ) is to hang from a float in the ocean, allowing it to take constant video of undersea life. The camera is relatively heavy; it weighs 40 pounds and has a volume of only 0.3 f t 3 . It is to hang 2 ft below the float on a pair of wires, allowing it take video at this constant depth. The float will be cylindrical, have a specific gravity, sg = 0.15 , have a thickness of 6 in. What is the minimum diameter of the float? Note that for the minimum float, the waterline will be coincident with the top of the float. If the float is made of a larger diameter, what will happen? If the float is made of a smaller diameter, what would happen? Figure 5.36

Escape from a Sinking Car
Assume you are in a car that ran into water and is sinking.
The car door is 43 inches wide and 24 inches tall. Assuming you can push
90 lbs at 28 inches from the door hinge. At what water height on the door
would you be unable to open the door?
Use Weight Density of water = 64 lbs/ft³.
Water Height =
in.
Please show me FBD, so I can understand it better. Thank you!
