What is the bird's trick anyway? How does it happen that she pulls the hippopotamus? And how does the hand lift the cabinet? And how do you crush a nut? After all, there is no extraneous engine in all these experiments. But the strength is still increasing.

The point, of course, is that the ends of the lever have different lengths. After all, we moved the pencil very close to the hippopotamus. And then only the bird managed to lift this hippopotamus. Still, she descended from a great height to lift the stubborn hippo barely a centimeter!

And the closet was also raised quite a bit. And the hand made a big move! So it turned out with scissors, and with tongs for nuts. The bird can only lift the hippo by grasping the long end of the lever. But she still has a long way to go. And the hippo moves quite a bit.

Bird's trick

It turns out that the strength of the bird increases as many times as its end of the lever is longer. Actually, not the end, but the entire part of the lever from the fulcrum to the end, to the place where the bird sits. This part of the lever is called the shoulder. So, if one shoulder is twice as long as the other - and the strength also doubles. The shoulder is ten times longer - and the strength is multiplied tenfold!

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 ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

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. ... >>

Electric school bus 18.11.2017

Daimler, the parent company of Mercedes-Benz, through North American subsidiary Thomas Built Buses, has unveiled its first electric school bus, the Saf-T-Liner C2 Electric Bus, with a range of 100 miles (160 km) on a single charge.

Daimler has established itself as a leader in the electrification of the larger and heavier land transport segments. Its portfolio includes the Mitsubishi Fuso eCanter electric truck with a range of 97-129 km on a single battery charge. And in October, Daimler unveiled the E-FUSO Vision On, a powerful truck concept with a payload capacity of up to 11 tons and a range of up to 220 miles (350 km) on a single battery charge. The company used the experience gained in these projects to create an electric school bus.

"Starting in 2019, the Saf-T-Liner C2 Electric Bus, or "Jouley" for short, will deliver up to 81 kids to schools across America safely, quietly and without emissions. A 160 kWh battery provides up to 160 km of driving range. Additional batteries are optionally available for longer range without recharging.During the development of the Saf-T-Liner C2 Electric Bus, Thomas Built Buses was able to leverage Daimler's advances in electrical technology (for vehicles)." manufacturer's release.

School buses are ideal for electrification. They are not as heavily used as buses on city routes - often parked for long periods. And their routes tend to be short, so a run of up to 160 km on a single battery charge will be enough.
