A cylindrical column made of 304 stainless steel and 3m high must support a load of 1000kg. It is recessed in the ground and free in the upper end.a) Calculate the compressive stress, then the minimum diameter of the column to respect a safety factor of 3 on the elastic limit. Answer for a) = Compressive stress = 86.78 MPab. Given the nature of this installation, this column is at risk of buckling. Calculate again the minimum diameter necessary to respect a factor of safety of 3 on the critical constraint.

A high-pressure gas cylinder contains 50.0 L of toxic gas at a pressure of 1.40×10^7 N/m^2 and a temperature of 25.0ºC . Its valve leaks after the cylinder is dropped. The cylinder is cooled to dry ice temperature (–78.5ºC) to reduce the leak rate and pressure so that it can be safely repaired. Show your work. a. What is the final pressure in the tank, assuming a negligible amount of gas leaks while being cooled and that there is no phase change? b. What is the final pressure if one-tenth of the gas escapes? c. To what temperature must the tank be cooled to reduce the pressure to 1.00 atm (assuming the gas does not change phase and that there is no leakage during cooling)? d. Does cooling the tank appear to be a practical solution?
