Exercise 7.2 A marble column of 2.0 m height and cross-sectional area of 25 cm² supports a mass of 70 tons. Young's modulus for marble is 6 x 1010⁰ Pa and the compressive strength at the fracture point is 20 x 107 Pa. Find: (a) the radius of column; (b) the compressive stress applied to the column; (c) the shortening of the column; (d) the maximum weight that the column supports.
