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

For example, water. In its liquid state we drink it , in its solid state (ice ) we use it to make our drinks colder or t numbs pain when wrapped in cloth and it’s gas state ( water vapour) we steam vegetables. In conclusion many different properties of matter are used for various purposes
Answer:
A
Explanation:
A common example of heterogeneous catalysis is the hydrogenation reaction of simple alkenes. The conversion of ethene (C2H4) to ethane (C2H6) can be performed with hydrogen gas in the presence of a metal catalyst such as palladium (“Conversion of Ethene to Ethane with Hydrogen and a Metal Catalyst”).
Answer: 2d
Explanation:
Because you can not make a 2d
It’s tropical. You’re welcome for the hint
