QUESTION 3 Following equation for the allowable stress in th

QUESTION 3 Following equation for the allowable stress in the column can be derived from Euler formula cr 2 This equation is true only for slender columns. Which of the following is slender column? OL Steel column with the slenderness ratio of 50 O Il. Steel column with the slenderness ratio of 100 0 Ill. Steel column with the slenderness ratio of 150

Solution

Euler equation valid for long or slender columns. Euler\'s formula is not valid for mild steel column when slenderness ratio less than 89. That means slenderness ratio should be greater than 89. Based on this data answer is 2 and 3
