A steel bolt 8mm diameter fits loosely inside aluminum tube 8mm diameter and 16mm outside diameter.A knot is fitted onto the bolt and tighten against the tube until the stress in the bolt is 40N/m^2.Calculatebthe stress in the bolt.If the temperature of the assembly is now increased by 100°C,what will be the new value of stress in each components. E=200kN/mm^2 for the steel E=70kN/mm^2 for aluminium And coefficient of linear expansion per degree celcius of both steel and aluminum is 10×10^-6/°C and 20×10^-6/°C

Pressure Vessels

The term pressure vessel refers to a closed container that contains gas or liquid at a different pressure than environment pressure. The pressure vessels have a wide scale of applications in our day-to-day lives and other industrial places. Some common examples of pressure vessels are gas cylinders, autoclaves, compressor vessels, etc.
