A hollow, circular steel pipe has an outside diameter of 350 mm and wall thickness of 10 mm. The inside of the pipe is filled with concrete and is used as a short column. The column is 3m long and is subjected to an axial load of 3,5 MN. Esteel 205x109Pa; Econcrete 14x109Pa Calculate: the stress in the concrete, the stress in the cast iron; the deformation in the column due to the load. 2.1 mm 14.5 MPa
