Question

A hollow column of C.I. whose outside diameter is 200 mm and has a thickness of 20 mm, it is
a 4.5 m long and is fixed at both ends. Calculate the safe load by Rankin’s formula using a
factor of safety 4. Calculate slenderness ratio and ratio of Euler’s and Rankin’s Critical load.
Take σc = 550N/mm2
; a = 1
1600 ⁄ ; and E = 8 × 104N/mm2
