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.

An automobile engine has a valve spring is to be made of Fe, C, & Mn, to be oil-tempered, & to be designed that should not exceed to a cylindrical space of 134-in in diameter. The spring index should be 6.0, the coil-to-coil distance of 0.33in, & the maximum load it will sustain is 100lb with the corresponding compression of ½/2-in. The spring is subjected to repeated loading & fatigue must be considered by a factor of safety of 2.25. Determine: (a) the diameter of wire based on commercial sizes; (b) the total number of coils; (c) the free length of the spring. Sample image of valve spring in an assembly.
