5.Find the Euler's crushing load for a hollow cylindrical cast iron
column, 15cm external diameter and 2cm thick, if it is 6m long and
hinged at both ends. E = 80GPa. Compare this load with the
crushing load as given by the Rankine's formula, using
0.= 550MPa and a =1/600. For what length of the strut of this
cross-section does the Euler's formula ceases to apply ?​

Answer 1

can you pls solve my question

Answer 2

Answer:

Given data: External diameter = 150 mm, thickness = 20 mm, length = 6 m, E = 80 kN/mm2, a = 1/1,600 and fc = 567 N/mm2.
