The given expression for Euler's crippling load (P) is applicable to which of the following column end conditions?
Consider that, L = actual length of column, E = modulus of elasticity of material and I = moment of inertia of column cross-section.
\(P = \frac{EI\pi^2}{4L^2}\)
1
One end is fixed and the other end is free.
2
Both ends of the column are hinged.
3
One end is fixed and the other end is hinged.
4
Both ends of the column are fixed.
