When a wagon or car makes a turn, something pushes you against the outer wall. You already know whose jokes they are. Centrifugal force is at work here, the force of inertia, which makes it move further straight.

But after all, the force of inertia acts on the entire car, on the entire car. So, she wants to dump him out? Yes, it strives. This is why a car tends to slow down when cornering. How not to roll over! And on tram lines and railways, in places of turns, the outer rail is laid higher than the inner one. And the car at the bend leans slightly inward. It turns out that a wagon slanting to one side is more stable here than standing straight!

Yes, you yourself, when riding a bicycle, lean inward when cornering. You do it unconsciously, without thinking about the force of inertia. Otherwise, it simply does not work, otherwise you will topple out!

Easier on turns

Highways are usually made inclined at turns. The outer edge is higher than the inner edge to keep cars from rolling over.

On tracks for bicycle and motorcycle races, the slope of the path in the corners is especially noticeable. There's a lot of speed there. And in the circus, sometimes you can even see such an attraction: motorcycle racing along a vertical wall. The track is arranged like the walls of a drum. Motorcyclists first accelerate on the ground, in the middle, circle faster and faster, lean more and more ... And now they are already entering the wall and rushing along it, lying horizontally in the air!

Easier on turns

Not everyone will be able to see this attraction, because it is shown not so often. But everyone can do a similar experiment with a ring rolling in a bowl. Take the bowl in your hands, put the ring on the bottom and begin to slowly shake the bowl so that the ring rolls in a circle. Faster, faster, and now the ring, noticeably leaning inward, runs along the walls of the bowl. And if the movement slows down, the ring will describe smaller and smaller circles.

Easier on turns

Having practiced well with a ring, you can try to do the same experiment with a coin.

By the way, with a very fast movement, a coin or a ring can completely roll out of the bowl. There is little trouble here. But on racing tracks, it also sometimes happens that a careless driver flies over the edge with his car. Now that's a big misfortune.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Ring Pet Tag gadget for finding a pet 14.09.2023

Ring, an Amazon company, has announced a new accessory called the “Pet Tag,” designed to help owners find their lost pets.

This accessory contains a QR code that is installed on the animal's collar. If a pet is lost, anyone who finds it can easily scan the QR code and thus help return the animal to its owner. Immediately after scanning the QR code, the owner will receive a notification that their animal has been found.

By scanning the QR code, the person who finds the pet will also be able to view information that the owner has previously specified in their pet's profile, such as its health status.

If the owner has activated the “Contact me” function in the pet’s profile, the person who discovered the lost pet will be able to contact him to arrange a return home.

It is important to note that Pet Tag does not have GPS functionality and is not intended to locate a lost pet. Rather, it serves as a replacement for a standard collar, which contains the owner’s contact information necessary to contact the person who found the animal. However, the "Pet Tag" protects the wearer's personal information and allows for more information to be added that would not normally fit on a standard collar.

The Pet Tag accessory is available for pre-order in the US for $9,99 and will begin shipping in early October 2023.
