CYLINDRICAL SHAPED TANKERS - The shape of tanker should have a low center of gravity and this can be attained only through a cylindrical-shaped tanker. A cylindrical-shaped container doesn’t have structural weak points that require reinforcing. Moreover, a spherical container counters the surging of liquid better as compared to other shapes. A cylindrical container is most favorable in extracting the liquid from the truck in an easier way than the other shaped containers. This is because the liquid gets funneled down to bottom of a cylindrical tank and even the least of drops flow out.

Cylindrical Shaped Tankers

Why Do Liquid-Carrying Trucks Have Cylindrical Shaped Tankers?

You would have often seen oil or water tankers in your city & surroundings and wondered why they are in such cylindrical shape?

Why these tankers only have a cylindrical shape but not cubical or some ideal box based shape?

·                     Greater Stability

A transport vehicle carrying liquids like liquefied flammable gases and oils needs utmost stability to transport them safely because the liquid has a property of agility.

For the commute to happen successfully, the correct shape of tanker matters a lot.

The shape of tanker should have a low center of gravity and this can be attained only through a cylindrical-shaped tanker.

The rectangular or square shaped tankers have comparatively a high center of gravity, which risks the vehicle’s stability.

·                     No weak points

A cylindrical-shaped container doesn’t have structural weak points that require reinforcing.

In fact, a rectangular or a square shaped container has corners and flat sides that can easily break under high pressure.

It means conventional rectangular container will lead to failure over time quicker than a cylindrical container.

·                     Sloshing liquid

When a tanker accelerates or de-accelerates, the liquid in the tank sloshes around due to the law of inertia i.e., “a body at rest remains at rest and a body in motion continues to move until an opposite external force acts on it.”

The phenomenon of sloshing is called as ‘surge.’

To reduce the surge effect while slowing down or accelerating during the travel, the tankers have metal sheets placed inside them that reduce the to-and-fro surging of liquid.

That’s why experienced drivers maintain a habit of slowing down or accelerating their tanker trucks smoothly.

Moreover, a spherical container counters the surging of liquid better as compared to other shapes.

·                     Extraction of liquid

A cylindrical container is most favorable in extracting the liquid from the truck in an easier way than the other shaped containers.

This is because the liquid gets funneled down to bottom of a cylindrical tank and even the least of drops flow out.

On the other hand, a rectangular tank would not allow the movement of liquid at the vent point and all the time some amount of product will always be left behind.

·                     Maintenance

A cylindrical container is easier to clean than any rectangular container because in a box-shaped tank the traces of liquid will get stuck at the corners and eventually be harder to remove.

A cylindrical container contains no such corners, therefore their cleaning is easy.

TRIANGLES USED IN ARCHITECTURE - The two most common triangular forms used in architecture are equilateral and isosceles. Triangles are effective tools for architecture and are used in the design of buildings and other structures as they provide strength and stability. When building materials are used to form a triangle, the design has a heavy base and the pinnacle on the top is capable of handling weight because of how the energy is distributed throughout the triangle. This is why many residential homes have A-frames; it provides a sturdy structure. The most sturdy of the triangles are equilateral and isosceles; their symmetry aids in distributing weight.

Triangles Used in Architecture

By Nicholas Ramos

Geometry and architecture are two disciplines that are fundamentally linked.

One of the most recognized geometric shapes is the triangle.

Triangles are identified by the three angles that are linked through line segments to form a three-sided shape.

The two most common triangular forms used in architecture are equilateral and isosceles.

Triangles and Architecture

Triangles are effective tools for architecture and are used in the design of buildings and other structures as they provide strength and stability.

When building materials are used to form a triangle, the design has a heavy base and the pinnacle on the top is capable of handling weight because of how the energy is distributed throughout the triangle.

This is why many residential homes have A-frames; it provides a sturdy structure.

The most sturdy of the triangles are equilateral and isosceles; their symmetry aids in distributing weight.

Equilateral Triangle

The equilateral triangle is by far the most common triangle used in architecture.

An equilateral triangle features three congruent sides and angles measuring 60 degrees on each corner. The lengths of the sides vary.

A common example of equilateral triangles used in architecture is the Pyramid Complex of Giza in Egypt.

Each of the four triangular sides that form the pyramids are equilateral triangles.

These are examples of the strength of the triangle in architecture as the pyramids have been standing for over 4,000 years.

Isosceles Triangle

Isosceles triangles, which have two equal sides, are also found in architecture throughout the world, especially in modern pyramidal architecture.

Isosceles triangles were used in the architecture of the East Building in the National Gallery of Art in Washington, D.C.

The building was designed by the famous architect I.M. Pei.

His architectural style featured the use of isosceles triangles and other geometric shapes.

The East Building was plotted on an oddly shaped piece of land.

Pei used an isosceles triangle also as the base of the building to accommodate the shape of the plot.

The Flatiron Building in New York City is one of the world’s groundbreaking skyscrapers.

This building is built on a triangular block in Manhattan, giving it a triangular shape, specifically, an isosceles. It has stood over 100 years, illustrating the strength of triangular architecture.

Scalene and Right Angle Triangles

A scalene triangle is one in which all sides are incongruent. Scalene triangles are not commonly found in architecture.

There is no symmetry in these triangles, causing an uneven distribution in weight. This is hazardous as one angle will have more weight and pressure placed on it than another.

Right angle triangles have one angle that is a perfect 90 degrees. These special triangles are not traditionally used in the structural characteristics of a building.

They are, however, vital to the construction and design of the building.

Right triangles are used to create perfect corners and straight lines. If the walls and corners of a building are crooked, the building also will be crooked.

Additional Information

Triangles are also used as adornments in architecture, not just in the foundational design.

In churches, triangular windows are often featured as window frames or in the stained glass, possibly representing the Holy Trinity.

The Hearst Tower in Manhattan uses triangular framing to add extra support for the tower and to frame the all-glass window structure; both equilateral and isosceles triangles are used.
