Question
A steam boiler, d meter in diameter and L m in length, is made of hard steel, generates steam at a gauge pressure of p N/mm2 . Assuming the efficiency of the riveted joints as e %. It is closed at both ends by flat cover plates which are made of Mild steel and freely supported. 1. Determine the wall thickness of the cylinder if the ultimate tensile stress = A MPa and factor of safety = B. 2. Calculate the minimum thickness necessary of the cover plates with uniformly distributed load, if the the yield point stress is C MPa and factor of safety of F. 3. Also find the increase in internal diameter, the increase in length and the increase in volume. Take E = 200 kN/mm2 and u = 0.3. d= 1.1 L= 1.54 ; p= 5.68 ; A= 328 B= 4.6 ; C= 494 ; F = 3 e= 69
