Why are Tanker Trucks Cylindrical
Many types of liquids are transported by road and rail. The tanks of trucks containing these liquids are cylindrical and non-cubic. Why is this so? If tanks are built in cubes or cuboids, their capacity will increase and they may contain more cargo. Even the large tanks used in refineries to contain petroleum products have a cylindrical shape.

This is
because the cylinders have no corners. Cubes and cuboids have more space, but
their angles make them unfit for fluid transport. When carrying liquids under
pressure, the stress in a corner is greater than the stress on the sides. For
this reason, stress is more focused on the corners. And because of that, there
is more chance for a tank to veil or break if it is cubic. There is less risk
of cracks in a cylindrical tank than in a cubic tank. Even the ends of
cylindrical tanks are made semi-spherical in nowadays modern tanker trucks.
LPG
cylinders used for cooking are also cylindrical. This is not to make them roll
easily. If you look closely, you will find that the LPG cylinders are not flat-bottomed.
The bottom of the cylinder had a false it is welded bottom.
This is why
all tanks carrying liquids are cylindrical. Another advantage is that liquids
can be easily drained into these tanks.
