The Engineering Marvel called Panama Canal

Did you know that a simple drought in the Panama region could cease the operation of the great Panama canal? This marvel of civil engineering uses a clever locking arrangement to lift passing ships by almost 20 meters in order to safely transport them across the canal.

To materialize this smart canal lock system a superfast concreting technology was needed. Look at the giant T-cranes the...
Inkjet Printers | The interesting engineering behind them

Inkjet printer technology is truly the magic of C M Y colors. The engineering behind the droplets and how the color algorithm creates the final image is pretty clever. We all know that display technology consists of minute red, green, and blue subpixels. As an experiment, one of our engineers at Lesics filled her inkjet printer with the same RGB colors.

Let's take a look at...

The Fastest train ever built | The complete physics of it

Magnetically levitated trains are common nowadays. However, the MagLev train the Central Japan Railway Company developed is quite unique and superior to the other trains. Running at more than 600 km per hour, it has achieved the status of ‘fastest train.’ This train uses superconducting magnets, which is why it is called SC MagLev. Once charged with an exciting current, the superconducting magnets of this train produce a circulating DC current and strong magnetic field...
The CRUEL Physics behind Tsunamis!

Tsunami waves that form in the open ocean travel at high speeds but are barely noticeable. Now, the wave is approaching the shore or the water depth decreases. How will the decrease in water depth affect the tsunami’s height? Surprisingly, the wave that initially seemed harmless suddenly gains a huge amplitude—a devastating tsunami. To understand this strange physics behind the tsunami, we should first learn about ocean beds that are constantly moving. ...
Boston Dynamics Spot Robot: All of its Engineering SECRETS!

A fall from almost 20 feet height - the Spot robot of Boston Dynamics looks like a dead creature now. But, it will recover like an intelligent animal with the help of its smart motor arrangement and intelligent mechanism. The angle of the Spot robot leg is quite interesting. It’s a backward bend design. Ohh, now there is one more robot to compete with the original Spot robot! The maximum speed both the robots can achieve is almost the same, but what about this stair...
Constructing the Wonder: Hoover Dam Secrets Revealed

The galleries located inside the Hoover dam are pretty amazing. They are responsible for draining water from beneath the dam body. However, if these simple looking galleries were absent, there would be devastating consequences for the dam. To better understand the clever engineering behind the Hoover dam, let's first explore how they placed the concrete in this dam.

Did you notice...
The interesting engineering behind the SHAPE of Train wheels!

The train’s wheels are not perfectly cylindrical, but slightly conical. In our opinion, this conical shape is a marvel of engineering that accomplished two major things, one - correcting the course of the train towards the center, and two - helping the train to achieve the differential action. To understand the first accomplishment, let’s consider a simple experiment with glued paper cups.

Underwater Constructions: How do Engineers Make Them?

Many laborers are fighting hard against the violent ocean currents to complete the construction of an underwater bridge pier. Are you able to spot a mistake made by the chief construction engineer here? This mistake will result in a catastrophe. Welcome to civil engineering’s most challenging task: underwater construction.

Even though we call it underwater construction,...
Airbags: How do they work?

This would happen in a high-speed accident if there was no airbag, even if the driver fastened their seatbelt.
It's a big engineering challenge to bring the human body to rest from a high speed in a time duration of 100 milliseconds without causing much harm to the body. Let’s learn about this life-saving technology by understanding the mechanism of airbag inflation, which interestingly happens thanks to a chemical explosion. ...
The MAGIC behind Da Vinci’s Self Supporting Bridge!

You give a collection of wood logs to the multi-talented genius Leonardo da Vinci, and in a few minutes, he will assemble a bridge from them. No permanent joints, and surprisingly, the more weight on the bridge, the stronger it becomes. Da Vinci designed this self-supporting bridge for troop movement.

Let’s arrange a few wood pieces as shown. It’s clear that the pieces...
