Crew members attempt to escape from a damaged submarine 110 m below the surface.What force must be applied to a pop-out hatch, which is 1.34 m by 0.669 m, to push it out at that depth? Assume that the density of the ocean water is 1024 kg/m and the internal air pressure is at 1.00 atm. Number Units A piston of cross-sectional area a is used in a hydraulic press to exert a small force of magnitude f on the enclosed liquid. A connecting pipe leads to a larger piston of cross-sectional area A (see the figure below). If the piston diameters are 4.20 cm and 56.2 cm, what force magnitude on the small piston will balance a 26.1 kN force on the large piston? Number Mi Units A a
