A) calculate the absolute pressure at an ocean depth of 1150 m. assume the density of sea water is 1023 kg/m^3 and that the air above exerts a pressure of 101.3 kpa. b) at this depth, what force must the frame around a circular submarine porthole having a diameter of 31.0 cm exert to counterbalance the force exerted by the water?

Abeverage can is made of 3004-h19 aluminum alloy (elastic modulus 69 gpa, tensile yield strength 285 mpa, density 2.72 g/cm^3). the dimensions on the can are approximated as a thin-walled cylinder with a height of 4.83 inches, diameter of 2.60 inches. empty the can has a mass of 14.2 g. determine: a. the wall thickness of the cylinder b. assuming a pinned-pinned condition what is the critical load? c. assuming a fixed-fixed condition what is the critical load?
