How does an MRI machine work?
You might have seen this on TV, or some of you might have even experienced this strange procedure first-hand. MRI scans are used in the medical field for diagnosis. In cases such as a brain hemorrhage, a blood clot occurs deep inside the brain, where doctors can't see. An MRI scan produces a very detailed 2D image of the brain, allowing doctors to analyze the damaged tissue and then perform their targeted surgery. Let's take a deep dive into how MRI imaging works and the principle behind it. ...

Chenab Bridge | How a Modern Engineering Marvel was Built?
The Chenab bridge has been hit by an earthquake with a magnitude of 8.0 on the Richter scale. Passengers might think that this would soon happen. What actually happens is different. The real deck remain unaffected by the earthquake. Can you explain how this is possible? The insert lies in a spherical bearing. The lower part of each bearing moves with the ground, but this motion does not transfer to the upper part. To isolate the real back the Chenab bridge also makes use...

Silencers | How do they work?
This part of a motorcycle, the silencer, is so important. Let’s operate the motorcycle, without the silencer to understand its importance. It is too noisy. Silencer helps to reduce the volume level drastically. Using an interesting analogy we are going to understand the complete physics of modern silencers in this video.
Let’s first understand how sound is generated and propagates. The air particles...

The Collapse of World Trade Center | The Complete Physics
The 9 11 terrorist attack - the huge impact force of the airplane did not cause the twin towers to have a tilted fall like this. Instead the towers stood strong for more than an hour. However to the world’s surprise the towers collapsed like a house of cards - a vertical fall! The main reason for this strange collapse was the tower's structural design - the perimeter tube design.

Why you should not PARTIALLY press the Clutch?
In manual transmission cars, some drivers partially press down on the clutch pedal to make the engine operate more smoothly. Some drivers even have the habit of resting their foot on the clutch pedal. This is known as ‘riding’ the clutch. However, do you know that this habit is really bad for your car?

Understanding Anti-lock Braking System (ABS) !
Nowadays an anti lock braking system is used in almost all modern vehicles. This system prevents accidents like this, where you lose control of the steering as you apply the brakes. With ABS you will be able to steer the vehicle properly and it also reduces the braking distance. What is ABS? How is it able to prevent accidents due to the braking? We will explore these questions in this video.

Mystery SOLVED - How did they Walk the Moai statues?
The Moai statues on Easter Island were transported a remarkable 13 km by the Rapanui people. These statues literally walked even though they didn't have legs. The mechanics behind this motion are nothing short of genius.
Consider this Moai statue. Imagine this statue is pivoted at one point. If you pull this edge backward, the other end of the Moai statue will move forward. Now by...

How are Bridges Built over the Ocean?
Please take a look at the foundations of a modern bridge. How are such gigantic foundations built? Especially when they stand on long concrete piles. Remember, the foundation is half submerged. To construct the foundation, engineers first need to install a watertight chamber, a caisson.
Let's observe the installation of this massive structure. Can you spot a major issue in this installation?...

Tesla Valve | The complete physics
A few commonly-used one way valves are shown here. All these valves have one thing in common: they all have moving parts. Here is a design challenge—is it possible to design a one-way valve without any moving parts?
Most of us will feel like this is an impossible design challenge, but not for design genius Nikola Tesla. Nikola Tesla has developed a one-way valve without any moving parts. In his...

Statue of Liberty : Even Today's Engineers are Surprised!
One of the biggest non-nuclear explosions in history, the Black Tom explosion, caused significant damages to the Statue of Liberty, but couldn’t topple it. The statue's strong iron frame is connected to the copper skin by these flat bars. Interestingly the flat bars are capable of flexing. What will happen in this design if a strong force acts on the copper skin? You can see the flat bars are bending. These flexible bars act like spring isolators and the force...

Comment sont construits les autoponts modernes ?
Dans ce magnifique autopont se trouvent quelques câbles d'acier à haut de tension protégés par des conduits. Malheureusement, ils sont en train de se corroder. Pouvez-vous deviner l'impact de ce phénomène sur l'autopont après 3 ou 4 mois ? Pourquoi cela se produit-il ? Vous ne le croirez peut-être pas, mais les autopons modernes utilisent ce type de poutre caisson vide pour leur construction. Il est intéressant de noter que l'ingénierie sophistiquée de ces caissons...

8 Choses à NE PAS FAIRE avec la BOÎTE de VITESSES AUTOMATIQUE
Au début, conduire une voiture équipée d’une boîte automatique peut sembler plus simple qu’avec une boîte manuelle, en effet les commandes de ce type de transmission sont intuitives et utiles dans diverses situations, comme dans la circulation où l’on s’arrête et repart après quelques secondes, ou encore en côte. Mais même si cela peut paraître une transmission élémentaire, il y a certaines choses que vous devez savoir. ...

The Brilliant Engineering of Mecanum Wheels!
Mecanum wheel-fitted robots or industrial machines can make a 180 degree turn without taking much space, whereas a normal forklift takes a lot of space and time to achieve the same task. Consider this perfect sideward movement of Mecanum wheeled machines. This would be tedious to achieve using normal wheels. Mecanum wheeled machines achieve all these crazy movements, but their wheels never tilt. Let’s see how Mr. Bengt Erland Ilon came up with this brilliant design. ...

Petrol (Gasoline) Engine vs Diesel Engine
Gasoline and diesel engines are the two most commonly used internal combustion engines. Even though their operation seems similar, they have some interesting differences, and each has advantages over the other. This video is aimed at exploring these differences and advantages from a scientific point of view.
Both engines have the basic 4 strokes: intake, compression, power, and exhaust. ...
