An experimental determination of the buckling load for 1.2cm diameter mild steel pin-ended struts of various lengths, two of the values obtained were: (i) When length is =50cm, the load is =10kN, and (ii) When the length is =20cm, the load =30kN. Make the necessary calculations and then state whether either of the above values of loads conforms with the Euler's formula for the critical load. Take E=200GN/m2
