Question 2
For a long slender column of uniform cross section, the ratio of critical buckling load for the case with both ends clamped to the case with both ends hinged is _________.
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
Question 4
The buckling load will be maximum for a column if __________.
