How does a Thyristor work?
The invention of transistors revolutionized human civilization like no other technology. At the heart of a smartphone lies a processor, and this processor holds around 2 billion transistors. What do these incredibly tiny devices do? How do they work? Transistors can act like a switch with no moving parts. They can amplify a weak signal. In fact, amplification is the basic function of a transistor. First, let’s understand the basis of transistors. We will come back to the application part later....

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....

Differential | How does it work?
Differential is an integral part of all four wheelers. Wheels receive power from the engine via a drive shaft and the main function of the differential is to allow these wheels to turn at different rpms, while receiving power from the engine.

What is a PCB?
A printed circuit board is the backbone of all modern-day electronic devices. Let’s explore what a PCB is and how these tiny circuits are manufactured. Let’s go!
Early electronic components were manufactured and connected to each other manually using wires in a point-to-point construction. This manual construction led to errors and difficulty in scaling up the production. Moreover, because these circuits were extremely complex, repairing one that had been damaged...

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...

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?
