3. During the design of spherical pressure vessel for space programs, a primary criterion is the mass of the vessel (which determines how much it costs to put it into the orbit). Given the stress in a thin walled spherical vessel is tensile and given by: Pr 2t where P is the pressure in the vessel, r is the radius and t is the wall thickness. For safety, materials will experience stress smaller that yield stress by a safety factor N. 10-1 Show that the minimum mass of the pressure vessel will be m = 2NT Pr³ P where p is the density of material. ys

Buoyance is an upward force exerted by a fluid that opposes the weight of a partially or fully immersed object. The upward buoyant force is calculated via the following equation: Fp = PfgV V is the volume of displaced fluid (object), pf is the density of the fluid, and F, is the buoyant force. 1) Calculate the buoyant force on 10 tons of solid steel completely submerged in water and compare this with the steel's weight with the density of 7800 kg/m³. (b) What is the maximum buoyant force that water could exert on this same steel if it were shaped into a boat that could displace 12m3 of water?
