The column shown in the figure is loaded by a vertical point load at its upper end. The column's self-weight is not considered. The cross section is trapezoidal in shape. a) Determine the dimension h numerically so that buckling in the y and z directions is equally likely. (2 p.) P b) Calculate the numerical value of the second moment of area in the situation of part a. (1 p.) A A c) Calculate the numerical value of the buckling load Pcr in the situation of part a.
