A hollow cast-iron cylinder 4 m long, 300 mm outer diameter, and thickness of metal 50mm is subjected to a central load on the top when standing straight. The stress produced is 75000 kN/m². Assume Young's modulus for cast iron as 1.5x 108 kN/m² and find: (i) magnitude of the load, (ii) longitudinal strain produced, and (iii) total decrease in length.
