Vajont Dam : The Deadliest Dam Tragedy in Human History
The Vajont dam tragedy - the massive tsunami from the dam wiped out many towns and villages, killing more than 2,000 people. Yet, the next morning, authorities were shocked to find the dam intact. If the dam remained undamaged, how did such a devastating tragedy occur?
That night, a massive landslide occurred on the south side of Mount Toc, moving at speeds over 90 km/h. You...

Jet Engine, How it works?
Jet engines have been the successful drivers of aircrafts for nearly a century now. In this video, we will explain the technology behind the jet engine in a logical, step by step manner. A jet engine keeps an aircraft moving forward using a very simple principle, the same that makes an air filled balloon move. Yes, Newton’s third law of motion. Just like the reaction force produced by the air moves the balloon, the reaction force produced by the high speed jet at the tail of the jet engine makes it move...

Three Gorges: How 40 Billion Tons of Water Shifted the Earth’s Axis
The water level is rising above the largest dam in the world, the Three Gorgeous Dam. The authorities have no choice but to open the spillways. It's a beautiful site, but can you spot a major design flaw? You're right. This water ejecting at high speed could erode the soil around the foundation. And finally, the clever engineering of these Chinese engineers install these concrete shoots. These shoots eject the water upward into the air where it breaks into small...

Why Resistors BURN OUT (and how to choose the right one)
Why Resistors BURN OUT (and how to choose the right one) This small resistor worth a few cents decides whether a production line worth millions of euros keeps working… …or suddenly stops due to a fault. The problem is that, very often, resistors are chosen or sized in the wrong way: they overheat, change value, and can even burn out. In this video we’ll see together why it happens, how a resistor really works inside the circuit, and how to choose the right one so you...

Torsen is a trademark of the JTEcht Corporation. The Torsen differential has many patented components and is the most unique and ingenious method of providing differential action while overcoming the traction difference problem. The internal components of a Torsen are quite different from that of a conventional differential. At the heart of the system lies a specially shaped gear pair assembly. Let’s see the cross-sectional shape of these gears at the mating point. As can be seen, one gear is a spur gear and the other one is a...
Understanding Wheel Alignment!
ThAll four wheelers, after having been driven for a certain distance, are supposed to undergo wheel alignment. What is wheel alignment, and what will happen to your car if you don't do it? Let's explore. At first glance, the wheels of a vehicle look as if they are perfectly straight and vertical and this arrangement seems logical. The surprising thing is that to improve vehicle performance, each manufacturer specifies some predefined angles to the wheels of their cars. In these exaggerated visuals,...

Understanding Limited Slip Differential
Consider a situation where a vehicle fitted with a standard differential moves straight, and one drive wheel is on a surface with good traction and the other wheel is on a slippery track. In a standard differential the left and right axle rotations are completely independent. Since one wheel is on a slippery track, the standard differential will make that wheel spin in excessive speed, while the good traction wheel will remain almost dead. This means high power supply to the slippery wheel...

The Biggest Mystery of Physics, How did Engineers Solve it?
On its opening day, the London Millennium Bridge began to wobble unexpectedly. You might observe something strange here: along with the sway of the bridge, the pedestrians are walking in a synchronized pattern. What’s happening here? Why are normal people walking with perfect synchronization? This experiment answers that question. At first, these metronomes are oscillating randomly. However, after waiting for a few seconds, they all oscillate in perfect harmony. What...

Immersed Tube Tunnels | Genius Engineering Under the Waves
The longest sea bridge in the world, the HZMB, suddenly disappears into the sea. Welcome to a modern underwater tunnel. Such tunnels are built using ingenious techniques that join different concrete elements. How do the joints remain leak-proof under tremendous hydrostatic pressure? This experiment provides the answer. I have filled the meeting region of the tunnel elements with oil. I can easily separate them out, oops. Now, let’s remove some oil using this syringe....

Sinkhole Physics : Why the Earth Swallows Itself?
The recent sinkhole tragedy in Bangkok, a faulty pipe rapidly eroding the soil beneath the ground. What happens is that the cavity becomes so huge and eventually… Why didn't the soil collapse when the cavity was small? This would have resulted in a minor accident. In fact, small holes do collapse. However, when the shape is curved, they don't. Arch-shaped structures can support much higher loads. If one fine morning, the doors of your house suddenly won't close, you should be...

Understanding Hill Start Assist!
Imagine a driving situation where you have stopped while moving up an inclined road and want to move uphill again. A few seconds are required to switch from the brake pedal to the accelerator pedal. As soon as you release the brake pedal, gravity does its job and the vehicle starts rolling backwards. Starting your car up a hill isn’t always easy.
Here’s a technology that has come to our rescue....
