Four identical hollow cylindrical cloumns of steel support a big structure of mass 50.000 kg. the inner and outer radii of each column are 30 cm and 60 cm respectively. Assume the load distribution to be uniform , calculate  the compressional strain of each column. the Young's modulus of steel is `2.0 xx 10^(11) Pa`.
