81.5kg student dared to climb a 20m wooden flagpole. Assuming the center of gravity of the student aligns with the axis of the pole and the pole has an elastic behabior, how high can they climb (in meters, m) just before the pole buckles? Neglect the weight of the pole. E for wood is 13.1 GPa and I=4.91(10^6) mm^4
