Fundamentals of Strength of Materials

A column with a length of 7.2 m has a tubular cross-section with internal radius 70 mm and external radius of 75 mm. It is to be used as a pin-ended column carrying compressive load along its axis. The material is steel with elastic limit at 250 MPa and Young’s modulus 200 GPa. Find out the maximum allowable axial load so that it does not buckle.
