Q1:

is the equation of Euler's crippling load if

A both at 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:A - both at the ends are fixed

The given answer is right. We know that Euler's Crippling load = π^2EI/L^2.

And if both ends are fixed L=L/2.
By putting the L/2 value in place of L, we get 4π^2EI/L^2.
