Question 2
If one end of a hinged column is made fixed and the other end of the hinged is made free, how much is the critical load compared to the original value?
Question 3
Four vertical columns of same material, height and weight have the same end conditions .Which cross-section will carry the maximum load?
Question 4
Which assumptions are incorrect in column theory?
Question 5
