The equivalent length of a column of length L having one end fixed at the other end hinged is

A2L

BL

CL/2

DL / √2

Answer:

D. L / √2

Read Explanation:

The effective length of a column with one end fixed and the other hinged isL/2L/\sqrt2. The crippling load for such a column is given by Pcr=π2EILe2P_{cr} =\frac {\pi^ 2 EI}{L_e ^ 2} , where Le is the effective length.
