Q1:

is the equation for Euler's crippling load if

A both the ends are fixed

B both the ends are hinged

C one end is fixed and other end is free

D one end is fixed and other end is hinged.

ANS:B - both the ends are hinged

L for column hinged at both ends = L.

So, when L is inserted into the above equation (Euler's crippling load equation) the equation remains unchanged.
