1. Answer:

   For a hollow circular column

   Area of the column,

   A=π4(D2−d2)=π4(3002−2202)=32672.56 mm2

   Moment of inertai of the column section

   I=π64(D4=d4)=π64(3004−2204)=282.62×106mm

   Section Modulus (z) =Iy=282.62×106150=1.884×106mm3

   Since the column is pinned at both ends

   Left = L = 4m =4000mm
