Practice Problem 10-4 Back | Index | Next

Given: An aluminum column (E = 70 GPa, Sy = 270 MPa) of length L = 4.0 m is loaded in a manner that permits free rotation at its ends. Let ro = 45 mm, and ri = 40 mm.

Req'd: Determine the maximum compressive load Pallow that may be applied if a factor of safety against buckling failure of 1.5 is to be applied.

Pallow =  kN  (1%)
