Question 1
Three columns are made with same materials and are having same cross-sections. One is hinged from both ends, second is fixed from both ends and third is one end fixed and other end free. If critical load of all of the columns is same then what is the length ratio for all three?
Question 2
For which one of the following columns, Euler’s buckling load 
Question 3
A bar of length 4 m when used as a cantilever beam, and subjected to a concentrated load of 30 kN at the middle, deflect 1.5 cm at the free end. When it is used as a column with same end condition as that of cantilever beam, the buckling load will be
