Gate valves and globe valves are both types of linear motion valves used to control the flow of fluids in marine engineering. Gate valves have a wedge-shaped disc that moves perpendicularly to the direction of flow, allowing them to fully open or close without obstructing the flow path. Globe valves, however, have a disc that rotates within a cylindrical body to regulate flow rate by varying the size of the opening. Globe valves are typically used for controlling fluid pressure and flow direction.

A steel column 3 m hight is of hollow square section, 200 mm outside dimension and 20 mm wall thickness. (young's modules E=210*10^9) calculate A: the compressive load which will give a stress of 60 MN/m^2 in column. B: the compression o the column under the load in (A).
