A 2.0 m long stone column has a cross-sectional area of 0.30 cm². The column supports a vertical load of 550-kg platform that hangs attached to the column's lower end. Ignoring the weight of the rod, what is the tensile stress in the rock and its elongation under the stress? Note: the weight is hanging, consider in solving for the force. Use a Young's modulus of 2.0 x 1011 Pa.
