Strength Of Materials Miscellaneous
  1. The rod PQ of length L and with flexural rigidity EI is hinged at both ends. For what minimum force F is it expected to buckle?

    1. π2EI
      L2
    2. √2π2EI
      L2
    3. π2EI
      √2L2
    4. π2EI
      2L2
Correct Option: C

Since both ends hinged, therefore, Le = L

Buckling load, W =
π2EI
L2


Also W = F cos 45°
∴ F =
π2EI

/ cos 45° =
√2π2EI
