Aspherical tank for storing liquid oxygen on the space shuttle is to be made from stainless steel of 0.80 m outer diameter and 5 mm wall thickness. the boiling point and latent heat of vaporization of liquid oxygen are 90 k and 213 kj/kg, respectively. the tank is to be installed in a large compartment whose temperature is to be maintained at 240 k. specify an appropriate insulation material and thickness of this material that will maintain oxygen losses due to boiling below 1kg/day assuming a combined convective and radiation heat transfer coefficient of 10 w/m2k.

unlike the threaded fasteners which are used to clamp the machine members, power screws are used to transmit power. common applications of power screws are: screw jacks: to lift weight. lead screw of lathe: for axial movement of tool and its precise positioning.

the warning light flashes for a second or two when the engine starts. if it stays on, there's must be something wrong with the coolant. you should never dare to continue driving when the light is on. pull over as soon as possible and shut the engine off.
