An Euler column is safely to carry a compressive load of 60 kN. The cross sectional
area is A=1452 mm². The radii of gyrations are rx= 14.75 mm and ry= 41.6 mm.
Knowing E= 200 GPa and that the ends are simply-supported all around, determine the
maximum allowable length L. Use F.S.= 1.92.
P=60x10³ N
