76. A column of height 1m has to support a bronze statue of mass 200 kg. Thecolumn breaks if stressed beyond 8 × 105 Pa.a) If the column has a diameter of 30 cm, will it be strong enough to supportthe statue? Show your calculation.b) If the Young Modulus of the material of the column is 5 x 109 Pa, determinethe compression of the column when supporting the statue.
