Calculate the crippling load of a strut of effective length 4 m according to Euler's theory for long columns. Take the modulus of elasticity of the material used in the strut section as E N/mm2 and the moment of inertia of the strut as I mm4. Consider that one end of the strut is fixed and the other end is free.
