The expansion diameters of the steel cylinder is 0.3mm
The expansion stress on the steel cylinder is 150MPa
<h3>Diameter of thin walled cylinder </h3>
t = Dp / 2s
low pressure cylinder of cast iron used for certain engine
t = Dp / 2500 + 0.3
wall thickness = 0.3 mm
p = internal pressure
d = inside diameter of cylinder
t = wall thikness
s = allowable tensile stress
<h3>The stress of the cylinder is</h3>
The pressure in a thin walled tube with diameter 0.3 m and thickness 0.001 m is 1000 kPa (10 bar).
The hoop stress can be calculated
σh = (1000 kPa) (0.3 m) / (2 (0.001 m))
= 150000 kPa
= 150 MPa
Hence , The diameter of the thin walled cylinder is 0.3mm
The stress of the thin walled cylinder is 150 MPa
